I've seen a lot of good advice on this subreddit, so hopefully you guys can help me out too. 

I have been with my girlfriend for over 3 and a half years. I knew she had self-esteem issues from the start, but I hoped to remedy that problem after being with her for quite some time. She was an athlete in high school, weighing about 110-ish pounds, being 5'2". Now we're going into our final year of college, she's probably around the 120-125 pound range, which is still nothing. Besides, I think it went to all the right places, haha. This girl is gorgeous. I'm not just saying that because I feel obligated, but everyone else thinks so too. I can't even leave her for 5 minutes when we go out and I leave to buy us drinks, because there will be another guy chatting her up and trying to put a move on her.

Her father wasn't exactly the nicest guy, and although he is out the picture now, him calling her fat when she was younger, even during the high school years, took a toll on her and her brother. Her mom, being the complete opposite, always called her kids beautiful and tried to counteract, but the years of damage done by her father overpowered it, I guess. So, I'm pretty positive that that's where the root of the problem is.

Basically, I have done every possible thing I can think of to prove it to her. She knows I think she's beautiful, and that she's a great person. But she refuses to admit that about herself. This isn't one of those "Oh my god, I'm sooooooooo ugly, give me attention." sort of things that some people do, you'll have to trust me on that one. She constantly feels like she's not good enough for me, which is wrong. We're in a happy relationship, my self esteem is fine, but hers isn't.

Is there anything any of you could recommend to me on what to do? Thanks in advance.
