Hi there violet09,
This
What your BH needs from you is honesty, transparency, and patience. Patience with his roller coaster feelings. Patience with him clinging, then accusing, then rejecting, then getting hopeless. Patience with no guarantees and no idea how long this will go on. You need to be the rock on which R is rebuilt.
is fantastic advice. I severely underestimated the timeline for healing, and my BS wanted to be all in. That 2-5 year timeline is no joke. For us it was more like 6-8. There isn't going to come a time when the infidelity is just over, in the past, it never comes up again. He still triggers once in a while.
Your BS has experienced a deep psychological wound. His triggers and the whole roller coaster thing are a normal reaction to a traumatic, life changing event. If he had had any other kind of injury and it wasn't because of your choices, would be having the same thoughts about whether to cut and run because you're not sure if he's going to be able to completely recover? I know the guilt is very tough for us WS to bear. It's not like we had great skills for dealing with difficult feelings, if we had we probably would not have cheated in the first place. When the consequences are raining down
it's normal for you to desire some certainty that it's not always going to be this bad, but that is actually a counterproductive way of framing the situation.
A more productive way of framing it for me was that regardless of what happened with BS and the marriage, I needed to work on becoming a safe person to be in relationship with and someone that I feel good about being. The ongoing work done to that end has been a huge positive for its own sake, even had our reconciliation failed, and I can say pretty certainly that without it reconciliation would have been impossible.
The name change thing is a no-brainer. It's a concrete thing he's asking you to do. My experience is that the longer you wait, the more of a source of frustration it will be for him that you are not honoring his request. It's hard, but the best thing you can do is let him know that you want to reconcile, let go of the outcome, and make a good faith effort to become a mentally healthy person.
If you don't already have one, a practice to help you cultivate a tolerance for uncertainty and the ability to sit with difficult feelings without acting out destructively or shutting down via numbing will help a lot. If you have any questions about that, just ask.
Peace and healing to you from this EvolvingSoul.
