Water -
I am so sorry you are having to deal with this. I know how much it hurts.

Even though you have every right to be furious right now, and of course every right to decide your own course (I often suspect I could never have stood as long as many of you have) -let me, in the spirit of compassion, mention a few things:
- her being pregnant does not change his actions. That is, he hasn't been more or less unfaithful just because she got pregnant. I know it makes it more uncomfortably real - but if you were willing to forgive his unfaithfulness before, why does this necessarily change that?

- this certainly explains a lot of his confusing behavior. Imagine his pain and confusion, being drawn back to you, having these wonderful weekends with you, wanting to return to you, but knowing he would have to tell you this fact which would probably cause him to lose you. Can you imagine how guilty and stupid he must have felt for screwing everything up? No wonder he was so depressed.

- obviously he doesn't really care for OW, if he hasn't rushed to her side to assume his responsibilities. One can only imagine his horrified response to this news, coming as it did just as he was waking from his fog and falling back in love with you.

Just some things to think about, Water.
Hugs
Ellie
