Long Run..just to let you know, H and GF were 8 mos. together, with I think, another month beforehand when he feelings I am sure. He wanted this to be a serious relationship, he talked about moving in....she broke up with him about three weeks ago. It was all very serious.
What I am saying is do not talk what your W says to heart. H looks happier than ever and is able to work on who he is.
I am sorry you find yourself in this sitch...become happy with you and where you are and your relationship with W will fall into place, whatever that R will look like, be it co parents, friends or spouses.
