ok, I know we say you H is stupid and immature and all that..and he is ACTING that way right now...but I gather that he is actually probably pretty intelligent and driven in the things he does. OW seems so young and just not on the same wavelength as your H. Just what I have gathered from what you write....so....I DON"T GET IT!!
My H and OW had things in common that drew him to her. Granted, she was a loser and he finally saw that...but I have to admit that there are things they have in common. Your H and OW seem to have nothing in common! Even more reason that their R would never work.
