I don't know what to do I know the age difference is not good?

Well, I've been talking to this guy. I'm gonna call him Dustin. He is 24 and I'm 16. Well Dustin and I met through a friend. My friend Christina, her boyfriend is bestfriend with Dustin and Christina has known him for awhile.Well she took us over there one day you know and i got his number and at first we were just friends, and I would go and hangout with him. Well one day a bunch of stuff happend with one of my friends and he flirted with them and I got really jealous and thats how he found out I liked him and we talked and he told me he didn't know I liked him and he likes me too, so he backewd off my friend. Then after awhile our relationship turned ual. Everytime I'm over there he kinda treats me as if I am his girlfriend, but not totally but idk he acts like he likes meI guess. I actually stayed the night at his house and when we went to bed he held me in his arms all night which was really cute to me. He also thought I was sleeping and kissed my head which was really cute and I looked up at him and smiled and said sorry for wakin you babe you just lookedso cute. I mean you just dont do that when your just friends with someone or if theres no feelings involved. I like him a lot, idk what to do sometimes when I'm with him he seems totally into me but then other days i just dont know. I know age is a huge problem, which him and I have talked about and we both know this is not okay. He told me he doesn't wanna be with me because of it and if theres really somehting there we can both wait and I totally agree. I don't know. What are your opinions on this whole situation? Please don't lecture me about the age thing!
