you're 25 and he's 41. he was 35 when you met. one way you might think about this, is that he might leave you for a much younger woman. just a thought.

knowing him 6 years, doesn't mean you are privvy to what really goes on in his marriage. the mistress is never aware. she can't be. the husband and wife have something going on behind those closed doors. and unless you can be a fly on the wall, you'll never, ever know the truth what is there. you could consider that, if you want to break it off. because if he's cheating now, he'll probably cheat again and you might be the one in the house with him. (if he leaves HER)

i wish you luck in your struggle. pat
