Sorry for the point-by-point, but there's a couple different things in your post that I wanted to address.
so im I crazy to sometimes believe that she truly wants to R..
Nope, not at all. We've all of us done stupid and hurtful things that we wish we could take back, or fix. Generally that hurt isn't on the level of infidelity, but we've all done it.
It is quite possible that she truly wants to R and simply doesn't have good relationship habits built yet so she keeps unintentionally hurting you. It's also possible that she's on the fence about R, but you're comfortable. Or that she truly wants R, but as a couple you're toxic for each other. Or that she doesn't care at all and is lying for her own selfish reasons. I think SI members could give you anecdotes about all three situations.
But none of us are in your exact spot right now, so all we can do is tell you about our own experiences and try to help you as best we can based on those.
I know im the only one who can decide what too do. But im I right in assuming most of you would be out the door already knowing what she did?
My wife carried on an affair with one of my best friends. A man who's often been described as "sharing a brain" with me since we aligned on so many hobbies, attitudes, even senses of humor. He was, for all practical purposes, closer to me than my biological brother. My wife lied to me, she hurt me, she (though she didn't realize it) threatened to take away my kids and home.
But I'm still with her. We're working hard on reconciliation. In the end I decided that I loved her enough to risk the pain of a potential failed R. And it's working alright, three months out. It's not perfect, and I'll be adding the affair to my catalog of mental scars, but so far the risk has been worth it.
I ask myself everyday if I will ever be able to get over what she did to me when I was in the hospital and everyday I come up with a different answer. I just don't know anymore..
To me, her behavior while you were in the hospital is the most hurtful action she took. Have you and she discussed why she did that, why she ignored your calls? Maybe as important, is it something she feels willing to explore with her IC, if not with you just yet?
