" The om, however, has been wracked with guilt and a few days ago has put the relationship on hold until he can move out. It's not the physical side that he's guilty about but the lying and deceit. I believe him when he says that he wants to build our relationship on trust. "
Oh, so you started fucking did you? Imagine what his wife would feel reading that bunch of ass blowing. I am a deceived wife and I found it hugely hurtful! Has it not occurred to you that his M difficulties could also be down to him? And no, your relationship will never be built on trust, and statistically it has a 3% chance of working. I think he is thinking better of it and has gone back to his wife.
come on guys, affairs are WRONG.
GGGB, "DH has not made any real friends ... He just wants to do everything as a family or with me and I feel trapped, stifled and bored a lot of the time. Kids are not easy and weekends spent with just the 4 of us often end very miserably! " it is just incredibly how much this crops up, isn't it?
THIS is what was wrong with our marriage, and he was furious if ever I brought my dissatisfactions up, and f*cked OW to passive aggressively tell me how angry he was. Well, it wasn't true love was it, or he would still be with her instead of dumping her the minute I found out.
And filled her ear up with the same stuff Discretion has been lapping up. 
Whatever wrong I did as a person, a woman and a wife, I did NOT deserve this level of pain and deceit.
Split up first, come on!
