A few days ago my girlfriend told me about this guy she knows from classes coming to visit her at the restaurant where she works. She was the only one there finishing up cleaning/mopping/doing dishes and stuff and said he came and talked to her for a couple hours. Apparently he has been calling her all summer asking to hang out with her (and she's been saying no), so he said something like "well I guess we'll only get to hang out if I come see you at work," to which she replied "....yeah.....umm...ok." She said she thought it was really weird when he actually showed up. If it were just this I would be fine with everything, but there's a little more. I'm not controlling and don't tell her what to do, but everytime she mentions hanging out/talking to another guy the hair on the back of my neck tingles a bit and I remember it. I remembered she had gone to breakfast/lunch with some dude last semester, and had also gotten help from him in a class. I asked if it was the same guy and she said it was. I also remember him calling her at one point when she was with me (she didn't take the call). First of all, it's a bit disconcerting that I'm only hearing about this guy now (after like 4 months). Secondly, some of her thoughts about the guy didn't all seem to add up: 1) She says he is pretty weird. 2) When she told me the story, I responded that the guy was most likely in it for more than just friends. She said she really thinks he's just looking for some friends. 3) At a different point she had said she had made it clear to him ("multiple times" was her wording), that there would be nothing more than being classmates. Why would she have to tell him this more than once, if she also thinks he's just looking for friends? Maybe I'm completely overreacting, but this kind of shit makes me uncomfortable, as much as I try to appear disinterested. If some girl was bugging me all summer long, I would have definitely mentioned it to her a long time ago. She also mentioned she's going to be in a class with him this term, and doesn't want to tell him to leave her alone b/c he is a "good student" and will want to work with him in the class groups. I don't think she has any particular reason to cheat. Even if there's nothing to it (probably true), I think she should stop taking advantage of this guy for class help. Should I blow this off, or approach her about it?
