Um...at 10 months out, you probably should be uncertain about R. 10 months is simply too short a time for a WS to change permanently.
Also, the following is awful, I know, but the steps backward into pain are the steps that enable quantum leaps in progress (alas, they just enable giant leaps, they don't guarantee them).
I have felt more inclined to R (and want to R quickly) because of how long ago the A was and how many years we have together that have been good. Of course, this also leads to the "being taken for granted" feelings I have, so it cuts both ways. As time has gone on I have "let go of the outcome" in my own way, and while I still desire R I certainly do not see it as guaranteed.
Gently, what's your objection to telling your W you are withdrawing because you want to process grief or anger, etc.? I think that is likely to be a good step for you.
Alternatively, you could just tell your W to assume that you're processing grief if you withdraw - but I think you'll find it more healing to let your W know each time. After all, if you tell her, she'll have a better gauge of how her A affects you.
The objection for me is that my wife for me is like Schrodinger's Wife - simultaneously my healer and my destroyer. When I am feeling like I need to withdraw, it's because I am stuck in the feeling that she is my destroyer and I do not want to interact with her. I do think you are right that ultimately being able to communicate even when I'm upset is healthier, but I am not there yet, and it felt very entitled of her to ask me to provide her that.
Further, the way she delivered the message was very indirect/evasive. I had come home after a very rough emotional day but felt so overwhelmed that I didn't feel comfortable around her or my kids, so I went to our room and laid by myself. Later, she said, "When you leave, I get really anxious and sick because I wonder where you are going and when you will come back to me. I would like you to communicate when you are leaving so I understand what's going on." My immediate reaction was, I didn't leave! I never went anywhere, I came home even though I felt like crap. She then said, "I meant when you leave emotionally as well physically; you check out emotionally and I may not see you for hours." That bothered me because it felt disingenuous. My therapist put it a good way - she is really asking for affirmation but cloaking it as asking for information.
I do feel responsible for providing information, I think that is fair to ask for, but she has all the information she needs - she knows where I am and why I'm there with high degrees of accuracy. I don't think I have any responsibility to provide affirmation, and that's really what she's asking for - affirmation that I haven't fully "left", either physically or emotionally. Would it be healthier to want to do that? Yes. But again, I'm just not there yet and I think she should understand that and not expect it from me.
Gratitude for things being good is not necessarily taking things for granted, but you say "status quo" - what does that mean to you? Does it mean that she goes back to not treating you with care and attention? Or does it mean she shows gratitude that things are getting better and she gets too happy?
What I mean is acting in ways that don't show care and attention, in ways that remind me of our pre-confession marriage. For instance, here's a reminder of a few setbacks I have disclosed here previously - her sending a "harmless" flirty text to our babysitter, writing an x-mas card to the family of one of her "lesser" OMs whose wife she is friendly with, and asking for permission to join a girl's weekend away. All these happened during a period of things going well for us, including this most recent blow up. Of course, it is a tautology that things have to be going well for a setback to happen in the first place, but it feels very much like how I described it in that it feels like she settles into old habits and forgets my feelings. The reversion to status quo to me means a reversion to normalcy, to ignoring/forgetting the pain I'm in, to not being sensitive to my triggers, to assuming we are back to being OK.
The reason I ask that is around the year mark, I came here and said I was feeling euphoric. And, I think it was really just because things had been so bad for so long, and the emotional pain was so heavy and hard that when I saw things getting back to normal I wanted to do cartwheels. Not because I didn't feel remorse, or because I was minimizizng what I did, but because even feeling a little bit good felt like a relief like no other I had in my entire life. And, a lot of it was I could see my husband was better too for little stretches of time. I was finally seeing evidence that we could fall in love again, that he could love me again.
I am telling you that because I think sometimes the BS panicks when this happens because there still debilitating pain and they see the happy stretch and they panic that the WS will forget or leave them behind? I can't really describe it. There are some here I think call it a vulnerability hangover.
I think this is very similar in our situation. I do feel a panic around happiness, in fact the very morning that my wife asked me later in the day to go on this girl's weekend, I actually said to her before we left the house something like "I am feeling happy but I am worried you will take that as a sign I'm not still hurting. I get scared to be happy because I feel like you forget my pain still exists." Not two hours later does she ask me how I would feel if she went away for the weekend with her yoga girlfriends in a few months! WTF?!
For us, I have already mentioned that 10-14 month period I was really, really starting to understand. That's because what you are describing was happening. I would feel all this hope and joy, and it would trigger the shit out of H and he would retreat. At some point, in watching this play out I learned the glimpses were just glimpses and that the destruction was far more devastating than I had even thought prior to this period. It was also the time that I was coming out of my own shame and really starting to get productive on my work. So, I think like you, he got those glimpses too of who I was becoming and it gave him hope too.
Now is a time to maybe start turning more towards each other and not being afraid to ruin the good day when it needs to come down several notches for you, and really truly share in what you are going through. For us, I was finally to the point I could hear him more clearly. It was a tremendous turning point.
I hope that this happens, we both want it to happen but struggle with how to get there. I think my wife thinks that she is further along in "the work" at this point than it sounds like you would describe yourself, but it is also less focused on her A and more focused on her in a general/big picture sense. Her A was also half a lifetime ago, so I think it's difficult to focus on it and the "whys" of her A as they are so distant and she feels so detached from who she was then, yet I'm in the thick of my misery about it as if it happened 9 months ago. Her focusing on her "big picture whys" makes it hard for me because she may be practicing things like finding her voice/being assertive/setting boundaries (with me), but practicing those things takes a lot of sensitivity in our situation or it can easily make me feel unloved/uncared for/alone with my pain. I (selfishly, I admit) want her work to be more focused on my needs right now than hers. I think sometimes she resents that, especially when she feels like we're ahead of where we actually are in healing.
