Feeling unwanted but knowing he somewhat like me

Okay so I’ve been friends with my since I’ve moved across the street. We chill, smoke weed and stayed friends. Well at one point we were really giving with each other and feeling the connection, we talked for about 4 months and not gonna lie we had sex twice but it was what we both wanted and needed so I wasn’t mad. Well a short while after he started acting different he told me it was because his family was making him think he wasn’t ready for a relationship as he had been cheated on prior to meeting me. We still have occasional sex and I know he likes it and me and want to be with me but he’s holding himself back and trying to gather his mental thoughts as he about to graduate and i’m a junior i’m already thinking about work and school. We still have communication and do the deed as it’s WONDERFUL ...... like I feel i’m in heaven, but I just worry about him and how he’s what’s he going to choose after high school, I tell him I’ll support him in any decision he makes and he acts so surprised I’ll do that for him and I had to confirm it to him that I’ve been supporting him and still will.
