<human>: Condense the text into a few key points

Long story: I moved from town A to town B right before High School.  I became friends with a small group of people in high school.  One of said friends was part of a club that I would sometimes attend to support him.  There was this girl a few years older than me who was dating someone else in that club.  I never actually spoke to her in high school, but she was mesmerizing.  I remember being quite envious of the guy who was dating her, I had wished I had the chance to hang out with her.  

Flash forward to after college.  I'm still close with all my high school friends, and at this point I've actually become good friends with the guy who was dating that girl.  They dated for 7 years!  I don't hang out with the guy often enough, but he is really cool and we are pretty close.  He has been through a few relationships since then and is now head over heels for a girl he is dating.

I recently met a girl online, and it feels like we are hitting it off.  It only took 2 msgs before I came to the realization that this is the very same girl my friend used to date! I'm really torn about this because I feel like I could really hit it off with her…the same girl I crushed on like 10 yrs ago.   I plan on telling my friend today and hopefully he is ok with me seeing her.  It would be reallllly hard for me to give up this chance, even if my friend disapproves.  What would you do in this situation?
