Guy problem!!! seiously need some opinions?

okay so i have a crush on this guy and last new years i was at a party and we ended up hooking up. afterrr that we never really talked (but i didnt have his number or any cles together or anything soo) but then i was at a party again and once again we end up sleeping next to eachother (nothing happend this time) but he woke me up in the middle of the night to go outside with him and ****. soo again i see him at my friends and in the morning we end up in the hottub together just hanging out and stuff. then the other day i built up the courage to facebook chat him and he asked me if id want to hang out so i ended up sleeping over his house and it was a lot of fun but still we never talk outside of the nights that were together? i dont know if it makes sense to you guysss but im just confused and i dont know what to think of this whole relationship haha, just any advice would be really nice!
