Just my .02 It doesn't sound like false R to me on the surface. It doesn't sound like you've chosen what path to take either. At a year out I did not know either.
FWIW It is hard for one of you to be trustworthy if other questions their sincerity. Even if the topic is avoided. KWIM ? What do his actions tell you about his intent ? If he is peaking to attorney then, well that is not the best sign. If he is investing in himself that tells you something about what he wants, for himself. The only way to ask him.
You are not going to get anything more than you put in. You are only going to get vulnerability to the point that you are willing to be vulnerable, etc.
I think if you are waiting for your BS to make that move first you will be disappointed. He was wounded by the A. He isn't going to be strong enough to make that move for a long time. He doesn't expect to have to be the one to take the first leap of faith. He trusted blindly and it burned him. If he does become strong enough and he still doubts your motivations and intents then . . .he might think about stopping trying altogether. Patience has it's limits.
Doubts are a normal part of R and any healthy M really. Bailing on the bad days ? THis tells me that you are willing to R only if you only have good days. You wanting to cut and run points to the fear is dictating your thoughts. Just like anger decision made with that in mind are rarely the "best" to obtain what we want out of life.
I have only one question. What are you afraid of that causes you to hold back ro to run away ?
Right now it sounds like you have agreed to "not D," that is not the same as R. You have agreed to continue the partnership as a financial and domestic arrangement. I have not seen many truly successful Rs where both people are not focused on the goal of building a new M.
It is a slow walk. The reasons I stayed in the M after D-day were very practical. It was not done out of love. Most days I did not think our M would survive either. It is a process. One that has vital steps that can't be accelerated or skipped over. It is not why I am M again today. If I or my W ran on "bad days" . . . we wouldn't be where we are today.
It comes back to fear. What are you afraid of? Is the fear of rejection, D or (insert other reason here) causing you more pain than the risk of being vulnerable is ? Living life in fear is not a good way to live.
JMHO. Your husband has recent examples to point to when he has these fears. It causes him to be guarded. The fear that you will repeat this behavior is very real to him. Any reasonable person would think that. Anyone who give him advice will likely highlight that point to him. He needs to rebuild himself without using you as a source of those feelings. I think him doing so creates a different kind of fear for him.
Again I think your fear is holding you back. I also think responsibility lies with the WS to be the one to take those first steps in order to provide enough safety that the BS can respond to in kind. The ownership lies with you to show that you are in this for the long haul.
Based on what you've shared here I don't see this as sustainable. Further I see you refusing to take risks when he already has taken some. What have you done to show that you really want the M ? Words aren't going to work here. What actions have you taken to show that your are trying to have a successful M ? Do you really want the M ? You can say you want it all day long, but do you really ? Nothing wrong with admitting that you don't.
There are probably things you have done, so please don't take offense to those statements. Sometimes to get what you want you have to take risks and be comfortable with them.
Separating finances. You have to admit as an objective observer no one, including your husband, would see this a step towards successful R. Further your actions are saying something different that your words. "I think we should separate things on paper, but I still want this M . . "
Do you see the inconsistency? Anyone that has a reason to doubt your motivations wouldn't see this as a step towards R would they ?
Take steps towards him. His reaction will tell you where his head is at. Further any time you want to "run" do the opposite. Engage. You will not resolve this M, D or limbo by doing that same thing that brought you here will it ?
