We've known for about six months and are pretty good friends. She is also good friends with my older brother who is dating her best friend. She's 20 and a sophomore in college and I'm 18 and a senior in Highschool. A few weeks ago I slept at her college house when she had a party and slept in her bed and we cuddled and kissed. Then did it again the next weekend. She had 3 other roommates in the room so I didn't want to make any big moves. But I really like her and want to be more than friends. Advice please?
