Bf being inconsistent.

My bf and I are both in college, except he’s two hours away. Although there’s some distance between us and we’re both busy, I always find the time to make sure he’s okay, give him the reassurance, and try to be as consistent as possible. But when it comes down to me needing reassurance, he always says I need to relax or I’m trippen.. he doesn’t call/ft me, he’s just completely distant and I’m tired of it. When we’re together and he’s back home, everything is fine but it always switches up when he goes back to school.

At times I feel like I’m asking for too much or I’m being too needy but giving reassurance isn’t hard, nor is finding a little bit of time to talk to me about his day. Idk guys I feel like I’m wasting my time and settling for less.... any words?
