A close friend wants to date me

I(24M) received a message from a close friend of +10 years saying that's shes thinking about the 2 of us dating. She's really pretty and a really good person , I have had a crush on her in the past but has given up because she wasn't interested in me, and she really liked 2 of my best friends since then. I don't know how I feel about the situation because I have moved on from her , but then again ive never been in a relationship before so this would be my first and I feel like that is the only reason im considering this relationship, which isn't a good thing . I've asked my friends about it and some said I should go for it while others said I shouldn't. Any advice would be appreciated.
