Alright, so I have been dating my gf for about 3 years. We have a pretty serious relationship and care about each other alot. Prom is comming up, and of course we are going together. Problem is, some douche decides he is going to ask my girlfriend to go to prom with him (he lives in a diff town, so prom is on a different day). This guy used to try to get with my girlfriend, but it didn't happen. She calls him her friend, and hangs out with him every now and then. We have talked about it 3 times, and on each occasion she gets really mad that i don't want her to go. I understand that they are going as "friends", but this guy really pisses me off. Honestly, does he not have enough respect to even talk to me before he asks her? I really hate that fact that she is going, and I think about it all the time. I mean, it is our own night, where we both get dressed up, look all good and stuff, just for one night for each other. But for her, she is doing it with another guy later, and I feel like i am having to share this with another guy. What can I do about this, is there really anything? I really hate what is going on and i just want to tell her that if she goes i am going to be really pissed off. I am also letting her know that this really bothers me, but everytime i do things get turned around and she ends up mad at me. She absolutely will not budge on this, and i think it would be easier for me to talk her out of prom with me rather than prom with him. Sorry for the long post...This is just really worrying me right now..
