I believe there is guilt both ways for an H...one way for what he did to his family and another for what he did to OW...I think they realize that they used the OW at some point and this is not easy to face...
Soooo...as I have said before...my H contacted OW a year after he was home...said he will "always love" her...I spoke to him about it after he started telling me that he loved me again...and about a year after that contact..and he said he didn't really feel that way and wasn't sure why he said that...for me, looking at the emails and thinking about that I realized by what she wrote and what he wrote he was really seeking closure...seeking to KNOW that she was okay...she was with an OM now and happy...I think this is what H needed to hear in order to move forward with me...he needed to know he hadn't screwed up her life too much...
So give H time...he sounds like a "nice guy"...as long as he is home and showing some progress...be patient...very patient...things will work out in due time...
