What should i do now?

Theres this guy and we've been friends for a couple of years now, and that works out pretty good. Sometimes i talk to him on the phone late at night for hours, and it seems like its been happening more often lately, and we talk about stuff thats not exactly appropriate, or like what you would think of 'friends' as talking about. He came to this new year's party yesterday and we were in the hayloft in the barn and we started making out. It was really great and then later we were watching the countdown and i sat on his lap the whole time and this one girl got really jealous.He also smells like my favorite cologne ever (hollister) and i cant quit thinking about him. I really want to be more than friends now, but i don't know if he actually likes me that much. He talks about how we can just be fwb sometimes and nothing more, but i don't know. What should i do now?
