<human>: Could you distill the essence of the text into 1-3 sentences?

My best friend, let's call her Ann, has been dating Bill for over a year now and he is a total loser. 

For a little background: Ann goes to college in NYC. Last summer she got an internship in Alabama where she met Bill. He is 13 years older than her and in my opinion just is using her for sex. At the time I wasn't bothered by the relationship and thought it would end when she went home to NY in the fall. 

But, a year later, they are still together. This is my dilemma, Bill doesn't have his life together. He has a part time job, has gotten a DUI, and doesn't have enough money to even come see Ann in NY. She is constantly flying or driving to see him. He is so needy and constantly calling or texting her. 

I just want what is best for my best friend and this guy isn't it. Unfortunately she is "so in love" that she just gets angry with me when I bring it up. How can I show her this relationship will never work?
<bot>: Bill is 13 years older than Ann and a thousand miles away and doesn't have his life together. How do I show my young friend this guy is using her for sex/nudes?
