Ok, I will address the rest later with any luck at all, but here are my thoughts on...
Quote: He was signing up on singles/dating sites within a week of our separation...he had no intention of keeping his promise!
I have looked at those sites too. I did it pretty soon after my W dropped the bombs on me. I never intended to, nor did I ever pursue anything there (really only checked in a couple of times and found it not something i wanted to be involved in) but I went there. Does that mean I didn't want to stick to my word to "not see" other people?
Could you, for the sake of us who are not familiar with your H's posts, post a quick summery of your sitch. I have no idea if this was a case of you having an affair, a simple separation, him having an affair, etc. I need some context and I am lazy today, sorry.
Also, I don't know if you realize it or not, but the individual sections of this site, i.e. MLC, Infidelity, Separated, now what, Piecing, etc, are all pretty separate in terms of who posts where. There are a few rare exceptions, but for the most part, people mainly stick to the section of the board where they have their thread. I say this to you because I am unsure if you WANT people who knew your H while he was here to post to you or you do not. In either case, it looks like he posted a lot in the "separated" section and not here, so most of us on the "infidelity" board will not be familiar with your story but should be able to help. Again, that can be good and bad depending on how you look at it.
