2 girls, who do i choose?

Last year i was in a relationship with girl #1 and i believe i was in love with her. She wa my "first" for just about everything and we dated for almost a year. now i wasn't the best BF ever i constantly nagged her about spending time with me but near...

the end of the relationship she was really rude to me and finally broke up with me after 9 months. after i tyyed to get her back by hanging around her at school and invited her over a couple of times during the summer(this didnt work)
About 4 months after we boke up (after i was shure i was over her) i started being friends with girl#2. We started dating and im shure im in love with her now but recently girl #1 started being nice to me. Just as im settling in with girl#2, Girl#1 dropes the bombeshell she really wants me back! today she wrote me a note explaing why she was so dismissve with me and sid she wants me to be happy and signed love at the end of the letter.
girl#1 was nie for a time but only seemed to start taking an intrest in me after i sterted dating girl#2(which i find is a sign of jelosy). girl#2 is a couple of years younger and as a result things ont get overly serious.
im gonna stay with girl#2, but want to know if you were in my situation would you completly stay away from girl#1, or try to be JUST friends with her.
im confused and could use any advise you can give !
THANKS
