Me and my girlfriend have been together for almost 2 years now, we've been madly in love for the first year and a half or so. However lately I've been having mixed emotions concerning her faithfulness to me. We broke up recently for about 2 weeks because she said i couldnt trust her (which i didnt at the time), but we did get back together and things have been going great. Its all about this guy she works with, she says hes just a really good friend but I think otherwise.. its not that i dont trust her, its that im afraid of loosing her.. she stays after work late once in a while, and she goes out with him at least once a week. Maybe im just a mad jealous boyfriend but i dont know what else to do, ive talked to her several times about this and she just keeps getting even more angry because she says i cant trust her. What else is there to do? How can i find the truth?
