Break Up Or Keep Going ?

So.. My boyfriend & I have been together for more than 4 months. We'll be 5 months on the 1st of Dec. he told me that lately he's been feeling distant & I know why. Its me. I don't treat him like before but its not because I don't love him anymore. I do. I love him so much. My love for him is great. He makes me so happy. The thing is.. I dont always see him. He lives kinda far from me. Different high schools. Haven't seen him in like 2 weeks or more. Every time we do see each other.. Its perfect. Nothing can mess it up. We have the time of our lives together. We've even talked about having our future together. He's the kind of guy I wanna spend my life with. Also, lately I've been thinking sice we're graduating in about 1 year 1/2 from now.. Well he's going to a college by my house but idk if I will be going there a university hours from home. Still deciding. I don't wanna lose him but then I don't wanna keep going knowing we'll break up because it'll just hurt too much. We wanna move in together but knowing how he is a momma's boy I'm also afraid his mom will interfere with out relationship. She doesn't know about us yet. If she did I think that would only complicate things. I'm Sorry this is long. I just really wanna know whay you guys would do or suggest. Just yesterday we agreed to stay together but I'm still thinking about it. This sucks but we can't keep living the fantasy that we'll end marrying & having a family & whatever else. Just wanna wake up. Or does this all just sound confusing? Be Honest. Am I just worried? I know I can keep going. Just afraid he'll give up before me. I don't wanna get hurt. Help please..
