Random Drama

Ok...I have some drama for you guys, but I really need some advise.

I'm 16 and I like this 14 yo girl who is really awesome. We talked for a while, but then told me that she really wants to be with me, however, I had no chance because she has a bf. I was ok with that as long as I had her in my life, until she told me that she had left out a piece of information. I was floored when she told me that her bf is 20 years old.

What type of shxt is that??? What type of loser can't get someone their own age so they take someone 7 years younger. Its ok when you both are adults, but when one is a freshman...c'mon. I don't really judge, but this really pisses me off.

I thought the rule/law thing was half your age, plus 7. Half of twenty is ten, plus seven is.....17 (go mental math). 

Anyway, I'm not writin this to hate on either one of them. I just need some advise on what should I do. Should I fight for her since I've known her for several years? Should I just give her sometime? Should I just forget about her? Post your advise.
