What should I do?

Well theres 3 girls that I like but I dont know which one I should ask out or if I should not ask out any of them.

Girl 1 - I’ve known her for about 4-5 years. I really love her and can picture myself marrying her and being with her for the rest of my life. Shes perfect in my eyes, almost. Recently I found out the she smoked pot :( bummer. When we hangout we always just end up talking for hours. When we walk around, it seems like we walk really slow. We’ve cuddled a few times and next time we hang out I think I’m going to kiss her.

Girl 2 - I’ve known her for about 2-3 years. I’m falling in love with her. She’s really pretty and has a great personality. I’ve only hungout with her like 3 times, but when we do hangout she has a real good time. We say “I love you” to eachother but I dont think she realizes that I actually mean it, ya know. We haven’t really done “anything” except hugging and I grabbed her butt once ; )

Girl 3 - I just met her in like december. She was in my gym class. She’s really funny and pretty. We havent spent anytime with eachother other than in class. I told her recently that I liked her but she said “she likes me as a friend just doesnt know me yet”. So obviously I know I’ll have to give this one some time.

But anyways, after reading all that. Who should I ask out??

Sorry for the long junk :(
