Ok need to vent. pretty sure my fiancee has been lying to me and hiding something. we got off the phone two hours ago so he could go to sleep. so why would he have been on facebook an hour ago? messenger is a big tattle tale when it comes to that and I don't appreciate being lied to. it's not the first time he's kept something from me and I've had a feeling since getting off the truck that he's not telling me everything. but everytime I bring it up, we fight and he asks me if he should not come home...ughhhhhhhhhhhh I hate men.
