Can someone help me with relationship advice?

So I fell in love in the beginning of September of '08 with another girl who is a year younger than me and have been in love with her since. She actually told me she was in love with me September of '09 but then our parents found out a wouldn't let us talk to each other or see each other at all and we weren't going to the same school anymore. She got her phone taken away and the computer. She got the computer back and phone eventually but then we started talking and she left me on my birthday last year. A few months after she subtly said she was sorry for saying a lot of rude things and things she did. She would leave me questions like over Formspring and Facebook sometimes but not directly at me, on her page. I've been in love with this girl for almost three years and it's pulling me apart. I think of every day and she's gone out with three other guys since then and each time it gets a little easier for me because I feel like I'm always hurting. I want to make a lot of money and get back with her someday. I know all this sounds a little bit crazy, but I love her. I honestly do. I'm a girl and it breaks my heart because I can't talk to anyone about it without being criticized. I haven't talked to her in about 8 months. Her family doesn't have a lot of money and her mom HATES me. Completely hates me... and I feel like I need to prove myself to her and the only way I can do that is with money. So I want to make a lot of money so I can help them. Does this sound crazy? Do you think it's worth it? I do love this girl and I know if we had a chance to be together again that she would take it because we loved each other until her mother took us apart.I just want to know if you think it's worth it? Any advice on what to do? I can't just talk to her because she seems happy without me... but I love her and am miserable without her. Help please.
