Learning to move on

So recently i've been feeling pretty good about life....this is a bad sign. Once I start getting comfortable something always happens, well guess what? something happened tonight. I don't even know how to express my feelings about this because I myself am so confused and I'm not sure what I should think or do. I feel like I'm taking steps backwards which I am I can tell. So once upon a time there was a girl I liked and kinda dated but not really because she wasn't sure about things and wasn't sure where her life was going, well anyway she moved away kinda randomly and kinda quickly I didn't get much a chance to see her before she left or spend time with her but she was doing what she wanted and needed to do. Well anyway needless to say I was left a little heartbroken and struggled to get over her. well I had been doing good, I even went out on a few dates tried to move on. Basically I saw it as, she's moved away i'll never see her again so why waste my time worrying about her because there's nothing I can do to fix things. Well like I said things were going good right? well tonight outta nowhere she starts talking to me on facebook. I could never bring myself to talk to her because I know talking to her would just make me miss her and make all those feelings come back, so I made myself a promise I wouldn't talk to her until I knew for sure I was over her or if she talked to me first. anyway like I said she started talking to me on facebook and she asked, "what I would say if she were back in utah?" I didn't know how to answer, I had so many thoughts run through my head. so all I said was "I would be mad that you didn't call me and tell me." and she continued to tell me she might be moving back in the ear future. once again I didn't know what to say. I didn't want to get excited and act all happy because I didn't know if she was just saying that because thats what she wanted me to say, but I also didn't want to be a jerk to her so all that came out was. "oh that's cool" of course she could tell something was off and she said, "you don't sound very excited?" you caught me!! what do I say to that? part of me wanted to be the mean guy and say nope I don't, because girls always want what they can't have right? so by saying that it would make her want me right? but I couldn't lie so of course my nice side came out and I said what she wanted to hear, "of course I still do." yes I was excited because I liked her and just by her telling me she's coming back makes me want things to work. but at the same time I wasn't excited at all because knowing she was here would just kill me, apparently all my feelings aren't gone for her. I hate how she controls me so easily with basically no effort at all, how she can make me miss her and want to be with her so bad just by saying she might be around. I hate how easily I care for people and let them get the best of me. I hate being the "nice" guy the "sweet" guy. It just puts me in bad positions, positions to get hurt while everyone else just takes advantage of you and use you however they please because they know you're nice and would do anything for them. there's so many things about her that I hate and it doesn't make sense because for all these things that I hate, you would think that it would be so easy to get over her, and it's not. All I want to do is move on and everytime I start to do just that, she has a way of reeling me back in. Learning to move on isn't easy and probably never will be but it's something I need to work on so I can live my life without worrying and eventually find someone that wants to be with me.
