Submitted by D.  – I suspect that my husband of 12 years is having a affair behind my back. I start to see sighs that a man is cheating like change of attitude towards our neighbor he used to have a good conversation but now he had something against her,he is trying to learn a different language like Spanish,he starts to walk the dog more often, he goes on porn websites to pick up women to have sex with, he lost 100.00 dollars of my paid check, and he is not in to sex with me now. what can i do to fix this. now he accuse me of it but i know that he is the one that is cheating. I have been faithful to him a through our 12 years of marriage and we have 2 kids together.
