Hello everyone. I'm a newbie here.My boyfriend and I have been together for 5 1/2 years and 3 months ago I moved in with him. I've never been suspicious of him cheating on me in our entire relationship...until now. See, there's this woman at his work and he's talked about how "cool" she is and how much they have in common and they also became friends on Facebook and have posted on each others' walls. He even told her on FB how much he appreciates her and how much her checking on him when he had to miss a day of work meant to him. He's also been acting "different" and now he's turning down sex, but one night he turned it down I saw him on the computer when he thought I was asleep "doing something" while looking at internet porn. I don't know what to do...on the outside everything seems fine between us (except no sex) but this is driving me crazy.What does everyone think? Am I just being paranoid or what? Thanks so much!
