My girlfriend who I've known for about a year and a half and just starting dating seriously about April, has a friend Sean who moved back in town not too long ago. I've met him when he first came back in town, but now I found out that he has other motives than just being friends with her. For example, he came in my bar (I'm a bartender) with a few other people after our last call last night while we were cleaning, and he was acting strange. I said "what's up" to him, but he seemed to act like he didnt hear me, so at the time I thought nothing of it. Well tonight, about an hour ago, we get home and my girlfriend is getting sick and her text messages go off, so she wants me to look and see if its her brother texting her, since he was out also. Well, turns out it was that guy Sean and of the 2 messages, the first said you should come see me, then the next one said "why don't we start fucking?". So I told her it's not her brother, but rather Sean and I read the message to her. She had a blank look on her face and said "i'm not the one doing anything wrong" and "I'm not and would never cheat on you", and "I wouldnt do anything to mess this up, I won't let that happen". I would be more hesitant to believe her if we weren't together 7 days and nights a week. As far as this asshole Sean goes, how should I deal with him? Should I: A: Sit there and make her confront him where I can hear or see by phone or in person? B: Should I text him back from her phone saying something like "This is (my name), you're not going to be fucking while she's dating me asshole so you need to stay the fuck away from her" C: Do that from my phone instead of hers D: Confront him in person or by calling from my phone E: Other (suggestions please) I trust my girl, but I don't trust this guy. Friends of opposite sex don't call after about 1 am for anything other than a booty call, for a ride, or to make sure they are home ok, am I right?
