Yes what to do if you suspect your husband of almost 2yrs cheating?see we have this unusual arrangement were married but i have a girlfriend that lives with us but i approve of her we all live together and have children but the past several weeks ive noticed a woman from his past i do believe she is his ex fiance from years ago anyhow she wrote a letter i confronted him on how she got our address he blew it off saying he doesnt know and now our cell phone number which is also unlisted and private someone will call arounda specific time this past week when i answer they hang up i think its her calling for him.however i did walk in and over hear him say something about seeing if the passion was still between them i asked who he was talking to he said business.do i need to be worried he seeing her or trying to?

Sounds kinda funny to me. Bad thing is, if you continue to accuse (maybe not outright, but second guess him, or throw hints) him of something he is or is NOT doing, he's gonna get more and more annoyed with you. So you can't always assume that because he gets upset he's guilty. My advice to you would be to wait until you have something really solid to confront him with.

however i did walk in and over hear him say something about seeing if the passion was still between them i asked who he was talking to he said business.

I know that I myself have jumped the gun at things I have heard my boyfriend say over the phone, only to find out it was absolutely nothing. The last time this happened, I was furious thinking I had caught him talking to an ex or someone completely new, only to find it was his mother, lol. I don't mean your husband would be trying to see if there was still passion between him and your mother-in-law, only trying to point out that things aren't always what they seem. Maybe you heard wrong, or maybe he wasn't talking about himself, or....maybe you heard right. You asked him about it, as you should have, and he said it was a business call, right? Ask him again, he will give you the same answer. Wait a bit and see what happens. If you truly love him, and have been able to trust him in the past, then continue to trust him until he does something that warrants losing your trust and/or your love.
