I hate stuff like this....and I totally understand your frustration, and I'm SO sorry you have to deal with this. What if you AND the girl complained about this guy? I know sometimes that hurts the situation more than it helps, but you never know.

I deal with stuff like this at my job too. It's a shame that people in the world have such messed up views on things we consider important. The most recent of my frustrations is a few guys at work saying that marriage is only some glass and metal (referring to my ring), and that never stops people from messing around, and I should feel free to do the same, blah, blah, blah. And it's one of my managers that is participating in this as well. THAT kind of stuff irritates the crap out of me.

I would certainly talk to someone if I were you. There's always the possibility of it making the situation worse, but you don't know unless you try.
Oh, and prayer.....always a good idea.
Here....I'm sending you a BIG HUG!!!! :)
