So I've realized lately that I haven't really given my gf the chance to earn my trust. We've been dating almost a year and a half (in 2 weeks will be the actual 1.5 mark) and I've always been a little 'restrictive' I guess. The only way I've been restrictive is that I don't like it when she goes out to parties without me. Anyhow. . .this has been leading to some trouble in our relationship. Tomorrow, her friend wants her to go to a frat house with her because she met a guy (friend met a guy, not my gf) and she wanted her to go with her to the frat to hang out. She said she 'didn't feel completely safe' and that she wanted another girl or two to go along to be safe. I got a little upset just over the fact that my gf is going to get all dressed up to go hang out at a house full of guys (only three girls going) yet she assures me she isn't going to flirt or anything. . . Do I have a right to be upset about this? If not (which I probably don't), how the hell can I get over this? It eats away at me and I don't know what to do.
