Could someone offer me relationship advice?

Ok, I will cut a long story short. There is a girl in my school, actually in the same class as me. We became close friends in around 2nd year, and ever since that time our friendship grow closer and closer. When I went home I could not stop thinking about her. Then the day came in 4th Year when for the first time she decided to sit and have lunch with me. I felt kind of uncomfortable, not because I had a problem with her but because she was sitting really close to me, and this happens to me, when I am around nice girls. So anyway I walked over to the vending machine to get water when she followed me over and stated that she fancied me. I was baffled, but I was really happy.





We then began to date, but it was not really successful, well it was kind off but we struggled to get really close, for a relationship that had lasted 6 months.





She then dumped me and I was distraught.





Then in 5th year she stated she still had feelings for me, and that she would love if we could go out with each other again. I never hesitated in saying ';Yes!'; to her, as I still had a great deal of feelings for her.





This time the relationship was great, we were a lot closer, and I thought this was the One girl who I could spent my whole life with.





But all of a sudden she dumped me again. This time I was even more upset, because I still had an immense amount of feelings for her.





She then had another boyfriend a year later. Although it only seemed to last for 2-3 months. But this hurt me a lot when I seen them together.





The question I would like to ask is that should I bother asking her out again? I really have strong loving feelings for her, and I still can't stop thinking about her, but I am weary as it may end in me becoming heartbroken again.





I have spoken to my best friend about this situation and he thinks it could do us both good if we were to get back together.





So the questions I am putting to you all is





Should I attempt asking her out? Which would be the first, since she has asked me out the other two times? or should I just attempted to move on, even though this is the only girl I have had these sort of feelings for?





and





What do you all think would be the best method of stating this proposition to her? A card, online, face to face, phone etc?











P.S: She has given me reasons for why she dumped me the other two times, and I have come to terms to why she did at that time.








Thank you to all who answer. :)Could someone offer me relationship advice?
I think that you could tell her how you feel. If you're serious about her, put your mind to fixing those reasons why she dumped you and tell her that you won't let them happen again. (And then, don't let it happen again.) Of course, if her reasons were petty, like, ';I think you're too sensitive,'; or, ';I wish your muscles were bigger,'; then she is an insensitive girl who does not deserve your love. Hopefully, though, there really are things that you can do better to win her heart.





You sound really hooked on her, and it is so sweet. If I were her, I would appreciate the initiative you would take to tell me how you feel. She has, after all, done each of the ';I fancy you';s, the asking outs, and the dumping. Stand up and take charge! Go for it! What have you got to lose, but then, what do you have to gain? This girl you're in love with!





Best of luck to you.
