I'm new on your thread and less than a month from DDay 1 (the "love") girl, and DDay 2 (the depravity). I also have 4 kids 6-14 that factor in to my perspective. I too had a wonderful marriage for 16 years and we were both very happy (well, I was). I have read your wife's thread and commented once to encourage her to keep trying. That's my full disclosure before I post.
First of all, everything you're feeling, doing, and saying resonate 100% and are totally legitimate and you can do whatever you want with it. Nothing I'm about to say changes that or my support of you and how you are processing things.
Second, the 90 day thing seems like a good idea, a really good idea. Finding out about infidelity is huge and I wouldn't make any major life decisions no matter how clear they seem without sitting on them for a bit. It doesn't cost you anything to give yourself, and her, time to process things. Look at how your thinking and communication has changed in a month and let it keep going until you get to your checkpoint.
Third, I disagree that you have to change or abandon things you value or parts of yourself to attempt a reconciliation. This implies a weakness in doing so. It takes incredible strength to consider R after a betrayal like this and a renegotiation of marriage terms. Renegotiation doesn't have to be a bad thing, however, unless you truly want exactly the marriage you had. That's OK too.
Fourth, (and this isn't true for everyone, and that's totally OK) for me, I feel like I can't leave and break the family (remember the kids whose decision I'm making for them) unless all possibilities for a healthy happy unit have been exhausted. This doesn't have to be immediate. But I have to be certain I've done everything I can to help heal this breach. Past the anger and hurt, is there anything you feel you owe yourself to leave without regret? It's easier to get on the D path than off it, I expect.
And finally, my WH is flailing and selling, and trying, and confused and scared and actually doesn't have the answers I need although he is frantic in his attempt to find them. He makes your WW look enlightened (this is not praise, btw). You have it worse than me with TT, I work at a place that does background checks for national security type clearances and when threatened with an investigation, my WH pretty much came clean in a few sessions. You haven't had that which sucks. However, there are facts and details and then there is the emotional side - why? How could you? How can I trust you? How can YOU trust you?
I think BS want/need those answers right away so we can make decisions and start to process. The problem is I don't think the first time WS has ANY freakin' idea!
I am NOT defending it, but neither am I surprised by the luke warm and contradictory emotional explanations you're getting. I don't think she knows, but I do think she's trying very hard to understand and give them to you.
So I will wrap this up by saying BS are owed a tremendous amount of emotional restitution regardless of the outcome. And we will never get enough and we don't have to forgive OR even listen. I just think the WS doesn't have the answers we need and deserve right away and I think the panic they feel right out of the gate makes the whole situation worse.
She's here, she's trying to understand and explain and she's taking what she sees as hits. (I got the "they're kicking me when I'm trying crap last night myself"
). You're here and you're trying to understand and you're actually defending her when you feel something unfair has happened. That's good for your healing process, regardless of the outcome.
Infidelity is really amazingly awful, but you're doing so well. You're thoughtful and responsive and you're listening to advise and making your own decisions. if you can consider the possibility that you can be happy with this woman, then do. If you can't, that's OK, but I'd let it play out a bit.
