I'm hesitant to even write what my intial thoughts are...saying that should give you a clue what I believe I'd do in your shoes...

however...

not being in your shoes the answer truly has to come from you.

can you live with things the way they are?
is it honestly impossible for h to get another job or to not see ow at his job?

In any case happy new year to you and a slap to h for being so foolish as to call ow on new years eve...as if you wouldn't notice. But then again if he hadn't been so foolish you may still be in the dark of wishfull thinking in regard to their r.
