Is my gf cheating? how would you handle this?

me and my gf have been together for about 2 years now.our 2 year anniversary is next month.since me and her have been together,it has been a long distance relationship.i would have to drive about 20 minutes to get to her place, then she moved farther and so i decided to move there with her. we fought only one time, the rest were little fits. now, i live about 40 minutes away. ANYWAYS...we have ALWAYS made it work, etc. but latley, everytime i call her phone, its always busy, she never returns my calls, so i got worried after a few days, went to her house to talk. we were totally good, holding hands, kissing, etc, but when we sat down she said she had sumthin to say. and she told me she went to prom with a guy, she kissed him once and doesnt talk to him anymore[we're both 18]and it was HIS prom not hers, thats why she didnt take me]anyways,we went a week for a break,things have been great until today,i found out she is talking to this guy again.i still wanto be with her tho.what do i do

it's weird cuz like, i feel like it's all my fault. when me and her are together we have soo much fun and we like, don't fight or anything. it's just since i only get to see her barely twice a week, she is just losing her feelings for me. if i were to move back down there, i am sure things would get better i'd like to hope. but at the same time i don't feel like i trust her or sumthin, like all i do is think about her and what she is doing all day and some days it will make me throw up. i duno im so lost on this. i cant just simply stop a 2 year relationship, you guys know how it is, its hella hard. =(

Her heart is with someone else, and there isn't anything you can do about it. Let it go, because she's not worth it. The world is full of women, and you deserve better. You deserve someone who can see you every day. You deserve someone you can make a life with. You deserve someone who doesn't lie to you and sleep with other men.

Let's be honest: the only reason you want to be with her is because you don't think you can do any better. That's called low self-esteem, and women can smell it on you a mile away. Trust me, it's a very unattractive smell, and as long as you think this way you really won't do any better.

Wasting your time with this girl is only going to hurt your ego more. Take control of your life, and go meet someone new. Someone who hasn't lied to you. Someone who hasn't played you for a fool. Someone who respects you the way you should be respecting yourself.
