Girl trouble

I really like this girl. We are so much alike and have so much in common..I believe I could fall in love with her. We have so much chemistry that it's truly incredible. Anyway, she does like me as well, I always knew she did when we were in school together, quite obvious..anybody could tell. She gave me all sorts of signs that she was strongly attracted to me. Like if I just looked at her, she would start blushing and smiling really big and giggling at the same time.

Anyway, I never got her number while I was in school with her and I graduated that year. I was so bummed out because really, genuinely liked this girl. Its like there's some unknown connection there between us. Anyway, I could never get over the fact that I just let her go, she would always come back to mind, so I got a friend that's still in school.. To approach her asking for her number for me. Haha wow he told me how she reacted..he said she was literally flipping out and she was like "No WAY" and that she couldn't stop smiling. When he asked her if she had a pen to write her number down, she started fidgeting like crazy going through all her stuff like she was extremely excited..and during this entire time she had a friend beside her that was talking to her and she was completely ignoring him!

Anyhow, we started talking just as friends. One day I ask her if she has a boyfriend and she says "Yes but me and him are not working out" so I ask what's wrong and she tells me that they barely talk and don't have much in common, and she likes me. Well one night we were talking and she admits that she has always had a huge crush on me. She tells me that her stomach drops and she gets butterflies when she goes to talk to me. She told me that I'm the most amazing person she has ever met! Well, I decide to stop hiding my feelings from her an I tell her that I like her and always have. Of course, she flipped out and was so happy. She had broke up with her boyfriend too. She texts me one night saying that she can't wait to see me and she has been thinking about us being together.

Well shortly after that, come to find out she starts dating him again! So this totally shocks me and has me confused. So me and her meet in person and I talk to her..trying to understand what's going on. Basically, she told me that she didn't know who would be right for, she thought that I would just leave her for some older hotter chick. I told her that I wouldn't do that to her and her "Well who do you want, who do you like more? I just want the truth" she looked like she was going to cry, her eyes started sparkling..she said, "You I want you" and I tell her then she knows what she has to do if she wants to be with me..break up with him. And has said she knows and she is going to, but its going to be hard because she feels sorry for him. She told me that's the main reason why she's going out with him..sympathy.

Anyway I walk her to her house and she told me that there's something she was wanting to tell me, but she was scared to tell me. Anyway I kept trying to get of out of her, and she asks me "well what do you think it has to do with?" I say "Is it have to do with how you feel about me?" When I said this she got all quiet and was staring at me. She started blushing and she got 'that' look again..like she was about to cry her, her eyes started sparkling. She told me that she think she's in love with me. She explained to me that when I graduated, she thought she would never see me again and that she never got over me. I always came back to her mind. She told me that I am the coolest Guy she has ever met.

Well, to cut to the point, she never broke up with that Guy like she said she was going to...and she basically chose him. She's still with him, all of this has completely shocked me and I just don't understand...I really don't want to lose her, because like I said, I know I could love her. What do I do? Please help..
