You got some major ass kicking to do OP

Dear OP, Uhh... okay, yeah. Soooo first determine this guy's relationship w/your girl there. If he isn't her best-friend, then you should tell her why *you* think it's a problem. Then second, tell Casanova there why you think it's a problem if you still find it sketchy (in private as to avoid any impropriety on your behalf). Maybe it's not a problem at all, maybe it is. Just take into account that boys have girls that are friends and girls have boys that are friends; these relationships can even involve love that does *not* include genital interaction. It doesn't always have an underlying romantic theme. You'll need to know if you're the possessive type, yeah? On both accounts; get to it!

chill out, your being paranoid, il bet the other guy is gay,

Okay, cool your jets everyone. For graduation, someone I didn't even know gave me a DIAMOND heart necklace. Someone I didn't know, to congratulate me on finishing high school. It doesn't mean anything. If she doesn't see anything wrong with it, you shouldn't either. Its just jewelry.

Your screwed

You wouldn't have any problem with it if one of her girl friends gave it to her. Girls can have lads as best friends too, doesn't mean anything it was just a nice gift of a friend.

That's not a guy friend hahaha

That's quite the assumption there 28. For all we know the gifter really could just only want to be friends with op's gf. What op should be more concerned about is how his gf isn't listening to how this situation has made him feel. Instead she's disregarding them by not acknowledging that this situation has op uncomfortable. At the same time, he could be overreacting at what may become between his gf and her friend. Since she doesn't view the gift as a declaration of love then there really is no threat there.

dump her you obviously deserve someome better because she doesnt realize anything wrong!

Dump her....
