((((OBG)))) This is how I felt for weeks. He seemed to be technically doing everything right and making progress. But I just didn't feel it.
In my case, my feelings were correct, and it turns out we were in false R for 3 months. I hope to goodness that this isn't the case for you guys. But I wouldn't discount your feelings. You know that you can trust your gut more than your WS at this point.
And if you're off base, discussing it openly and clearly with him could help him see what he can do to give the assurances you need. Maybe he's just feeling intense guilt and shame that makes it hard to be affectionate? Maybe if he knows it's affecting you he can work on it?
But he really needs to be reaching out to you at this point. Not only the other way around.
