ok. i'm 20 years old. and i have been thinking about a 15 year old girl alot recently. and i know that she likes me because we have talked about it. but, she's 15. and i really like her. i care for her so much. we have been talking for a while. at first as a friends sister, because that's what she was. then we got to become friends. and i can't seem to get her far from my mind. i've had some people tell me to wait untill she's 18. and others have told me to go for it, as long as i'm not just using her, and i've had some friends tell me to stop talking to her because she is so young. but 5 years is alot to me now, but it isn't so bad if the relationship progresses, right? i don't know what to do. got any suggestions?
