So my girlfriend of 4 years has started texting this guy from her new job. He's a married dude who has been talking to her about how unhappy he has been in his marriage and all of this other stuff. She's been telling me everything about this dude, how she thinks he's a whiny bitch, and we've been laughing about it. But now they've been texting each other a lot and I got really jealous when I saw his name pop up on her phone earlier today. I've talked to her about it, and she's told me that nothing would ever, ever happen with this guys, saying how I'm much more of a man than he is and how unattractive he is (he does look a little goofy), and even offered to cut off communication with the guy because of how I felt. She explained that he doesn't have anyone to talk to about his problems, but in my opinion whenever a guy talks to a chick it's usually because he wants to tap some ass, not because he wants a gal pal. Anyway, she doesn't really have many friends, and I don't want to be a jealous douchebag who controls who she talks to, but am I right to be a little upset about this? I don't want to ruin our relationship but at the same time I can't help but feel a little jealous. Anyways thanks for reading. Cheers.
