How do I save my marriage to husband in MLC?

[RLay1100]

H's A with OW seems to be coming to an end (maybe). They are exchanging nasty messages to each other on their secret Ms pages. Well, actually, SHE is being mean and he is acting like a wooped pup- "I wish you luved me half as much as you do him". blah He supposedly went and got drunk last night.

I texted him today asking if he was okay since he never even bothered to call the boys this past weekend (after he promised he would take them to some kind of bike race). Now, I know that he was too busy fixated on his OW and trying to keep the A going, he probably didn't even give the promise he'd made to his kids a second thought. He didn't text me back, which is odd- he usually does. He deactivated his FB page (an addiction of his), but then reactivated it 5 hours later.

I wonder what happens next? He falls into a deeper depression and this is his push on through the tunnel? I hope so.
I am feeling very hurt that he feels so much love for this young girl who is such a...bad person. He even mentions in some of his messages to her that she treats him [badly] and he feels like her doormat. That is exactly how I feel about him:-( WHY does he love her so much he is depressed that she doesn't really want him? WHY isn't he depressed that he doesn't have me in his life anymore? I have been his SO for 11 years...but that seems to mean little to him, but she can be some little tramp and have him feeling so much love he is willing to lose everything for her. ::sigh::
