Not sure where to start, Part 2

[wishing, hoping]

So again I wonder why I continue to stand for a marriage that H clearly has no interest in. He has no interest in me and sometimes I wonder if this whole thing is to punish me for something I did or something he thinks I did. What kind of person wakes up after an "emotional breakdown" decides they don't want to be married anymore but doesn't say anything for months and yet starts online dating? Then once the dating picks up drops their faithful unsuspecting spouse like a hot potato? Do I really want his guy back?

Counselor says he is running from reality because he can't cope. That may be true but I can't help but think that maybe I and my kids need stability and clearly he ain't it.
