Okay so I was going out with this guy for a year. I am usually very outgoing but around him I was so quiet and he's a really quiet as well. So we were going out and he was my first boyfriend and I didn't exactly know what to do at first. I didn't understand it so much and I always was too hard on myself about it. At turnabout (A High School Dance where the girl asks the guy) we were still going out and everything and I asked him to go with me. Of course, he said yeah. We got there and this other girl tried to snag him away. She had asked a different guy to go with her but he had said no. My boyfriend danced with her and I just overreacted, I know I did. I felt awful but he claimed that he couldn't find me and didn't want to hurt my feelings. I didn't talk to him for awhile and then we agreed to come back to my house to talk about it. We both apologized and it was okay. Well, towards the end of the year I broke up with him. I just felt weird and uninterested all of a sudden. He was usually way more into the relationship then I was. He took it very hard and kept on begging for me to go out. Nothing happened. We got back to his house one of the days after school and went swimming in his pool and did some stuff. Nothing that bad, but nothing that I'm too proud of either. So that whole summer I was playing the whole "Friends with Benefits" crap. Big mistake. The only reason I did it was because I was SO SURE he would ask me out again. I was basically just waiting. I liked him so much all of a sudden and he was all I could talk/think about. I went to Florida for a few weeks then with one of my friends. I came back to see that he had found a different girl. The same girl who took him away at turnabout and was always complaining about me to him. Do you think he might have had feelings for her all along? Or do you think he was upset nothing happened with us and just decided to move on? Do you think he will come back to me? He didn't tell me about them. I knew nothing. Absolutely NOTHING! I got back to school to see them talking all the time to her but of course I thought nothing of it. I tried to talk to him too but it just didn't seem the same. All of his answers and responses just seemed really short. I finally asked him what was going on and he said that he wanted to tell me but just didn't know how. He said But you can still call me and everything. (Thats keyword for sorry I moved on so maybe you should stay out of this?) I told him how much I liked him and that I still did but obviously it didn't matter because he still picked her over me. They're going out now. It always is that way, when he likes me a lot I couldn't care less when I like him a lot he could care less. I just hate seeing him with her it makes me feel completely worthless. I know that she will not give into what he wants like I did though. And I don't know if he will like that or not because he is kind of aggressive. It's confusing. But I don't really know what to do and it's just really awkward. I don't want it to be awkward I'd do anything to change that, I really would. It's just hard to find out how much you like them after they reject you. It really hurts. It really does. The only time we talk is online now... should I just stop talking to him altogether? But, as pathetic as this sounds I want to still maintain a friendship kind of. I want to be the rebound. I would go out with him in a second and I know that is wrong because he is being a jerk. Online once he was like "Yeah my girlfriend reminds me of you so much." So I'm hoping he realizes she can't be like me and want to come back to me again but I really just don't know. She is much more into the whole relationship thing. At least more than I was...
So yeah if someone could give some advice on this little issue that would be so helpful. I'm just confused and anything would help. Thank you :)

Well, There is a little saying "you want what you can't have".
The first sign of this was when you rejected him... He wanted you back, asking you to go out... and so on... but you had no interest and didn't care.
My advise for getting him to think...
Pretend you've moved on... All he needs to know is that you can make it with or without him, he needs to see that you have your own life, become that out going girl again, do things with your friends, don't let it show that it bothers you... and... this will bother him...
My advise to you...
Some of what you said, sounds like you may have done things with him that you didn't necessarily want to do??
If so, this is hard for a girls self-esteem. You shouldn't feel like you have to have intimate relations with a guy in order for him to like you, and if he was pushing you or making you feel that way... then he's not good boyfriend material.
Have fun with your friends and try to put him in the past... You will meet someone in the future who shares your same out going personality and you might find yourself a lot happier.
