What is my ex girlfriend doing to me?

My ex and I dated for almost three years and then we both went off to seperate colleges two hours away from eachother. We decided to stay together and try and make it work since I had my car at my college and I would go see her every two weeks. Well, after two months or so, she would be all depressed and upset because I wasn't there with her, which is totally understandable but there's nothing I could do about it. Constantly she kept on bringing this up (honestly I think she has to have a guy in her life to be right next to her to feel important or special) and after a while I told her that maybe we should take a break just to see what was out there. I did this because she just constantly calling me balling her eyes out and getting upset with me, even though I drove there like 4 times in those 2 months, it wasn't like I wasn't trying to make it work. So this break happens, but we still talked every single day, went to eachother's Thanksgiving in November, got eachother Christmas gifts, I still went down to her college to spend the weekend with her, etc. So I took it that we were still seeing eachother, kinda like nothing really changed. Well I take her out Valentine's Day to an amazing dinner and before that I surprised her by getting us a couple's massage, it was great. I planned on asking her out that night once again (cliche on valentine's day, I know...) so I ask her out and she said, "I'm almost ready to do this distance thing." That was her excuse all year when I tried to get back with her "I can't do the distance thing, I want a guy that I can just go over to his house in the middle of the week and study or just watch t.v..." which really made me upset because I can't do anything about that since I am two freaking hours away from her, but I'm doing my best to drive down there almost every weekend to see her, I freaking drove down there on a Wednesday night to surprise her because she was having a bad day, spent the night with her, and drove back to my college at 6am the next morning... talk about committment... anyway she said she was almost ready for this distance thing, which I was really pumped up about her answer because she was considering it. Anyway, the next freaking weekend... she meets this guy at his frat party that's now going to be a senior at her college, is greek, and is studying neuroscience. She tells me the next day she met this guy and he's hilarious and all this crap... then she goes on to tell me that we shouldn't say I love you any more, or talk as much anymore since we are 'technically' on a break. So of course, I freak out and get pissed because the week before she said she was almost ready to date me long distance again. So she starts seeing this guy, but she still calls me like everyday and tells me how drunk she got at his frat parties and how she's having so much fun, just **** I did not want to hear, but I listened anyway because I thought the more I listened and be her friend, the more chance I will get back with her in the future. Then the pictures came up on facebook of them partying and kissing and all this ****, so I deactivated my facebook because I couldn't handle that... it was like she was pulling me along on the ride incase her boytoy didn't work out she had me as a back up plan. And she told me she still wants to date me in the future, but right now she wants a guy down at her college. But then one night while she's dating this guy, she sends me a picture text of us when we first started to date and put a smiley face, and sent me Lifehouse lyrics saying I miss you, like I just did NOT get what she was freaking doing to me. It was tearing me up inside cause I see her dating this guy and I know I can't get her back, but she's toying with my emotions to stay in love with her. It was like torture. Plan up sucked dick. And I called her out on it and told her she can't say those things to me if we aren't together, well she gets all pissed off and upset and tells me she isn't over me and still want to be friends so we can date in the future. And I said, look lady, I cannot be your friend right now, because I do NOT want to get in the friendzone with you and have nof reaking chance with you in the future. She respected that, but still to this day texts me or calls me first, everytime. Always. I never call or text her first. She's been dating this guy for like three months now and I freaking feel awful about myself because he's older and she said he's more mature than me and tells me that since she's very mature (which I totally disagree if she totally mindfucked me for about three months) she wants a mature guy... and he's foreign, and studying neuroscience and is older and like 6'1. (I'm 5'7). Idk, I just seriously feel so shitty about myself and I just want to know what the hell she is doing to
