my girlfriend might be bulimic

some one pls reply i was just with her and i was sort of listening as she went to the bathroom, she was throwing up. im worried for her, she used to be so depressed and almost kiled her self. i dont want her going back to that

You seem like a great boyfriend. I would talk to her about it in private but NOT after she has come out of the bathroom, NOT during a meal, and NOT right before or after eating. Say something like, "how are you?" but in a very serious tone and looking directly in her eyes and let there be a long pause before and after she answers. If she just says "I'm fine" or something of that sort, tell her you want her to know she can tell you anything and that you know she's been under a lot of stress lately and that you want to be there for her. Verbally affirming this is always encouraging even if she already knows you are. ...

If that doesn't work, wait a week and then try confronting her again in the same manner but more directly, like "I heard you throwing up last night after dinner, is everything ok?"

I hope that helps some. Confronting someone is difficult but very important.
