This all starts back to november, me and my girlfriend are on a forced break up. She starts spiraling downward, and at 16 1/2 she becomes an alky.. She trys to get booze any way she can, and she got date raped two times, The second time it happened I swear I flip out, and try to do everything I can, she refuses the help, I learned that the reason she drinks in the first place is because its the only way she felt better

I figure, screw forced break up and if its gonna stop her from all this stuff, its worth it so i went back out with her, and In like a month we broke up like 12 times cause of her being all weird.. now shes hanging out with the dirt bags that I used to hang out with when I was a dirt bag and I warned her of what was to come, It finally came, and here I am upset over it, As Im talking to my freinds about this, her cousin blurts out, that when she was raped she didnt report it, and understands why my ex didnt... WHAT THE HELL IS WRONG WITH PEOPLE? Whats wrong with me? How do I get over this girl!?
plz help nothing is working.
