Navigating a Potential Long-Distance Relationship

I really like this one guy. We went on a few dates, I even opened up to him about my chronic illnesses and PTSD from how my ex treated me. We were working our way towards a relationship, we were talking about being a couple, but then we realized the semester was coming to an end, and we don't live close together when we're not in college, and we didn't want to start a new relationship and immediately be long distance. We decided to be friends for now, and if we still have feelings next semester, we'll try dating. I love being his friend, but I also deeply want to be more. It's definitely too early for me to feel like I love him, but I'm definitely getting there more and more every day. I'm so scared that he won't feel the same when summer ends. Idk if I should talk to him about this again (we already talked about it once and he basically told me he that rn he likes me but he can't promise anything about the future bc we won't see each other much and will kinda only text for the next three months). What should I do? I'm trying to distract myself and just enjoy his friendship for rn, but I just still just fall harder and harder for him each day.
