I think I'm to the point of ending it. I'm not going to make any rash decisions, but at this point I can't see us R. We don't have any kids. No property is owned together. All separate finances. It would be very easy for me logistically to walk away.
I'm guessing nobody here will think less of you if you decide that you don't want to be in the marriage anymore. As I've read many times, the LBS is the one that gets to decide when the marriage is truly over.
But I do think you really need to carefully think about that decision, because I believe without going through this process, there is no way to successfully heal the relationship. Sure, you could R at some point down the line, but it wouldn't be in a way that would be any different from how it has been in the past.
