Please help!!

My boyfriend lives an hour away, goes to a different school, and has really strict parents.We usually see each other once a week (on Saturdays bc he can drive and I can’t) but lately we’ve been fighting a lot and haven’t seen each other in a couple weeks. We were talking earlier and I told him that I feel like he’s changed. He denied it at first and said that he wasn’t any different. But we kept talking and he said that he didn’t feel like he was good enough for me bc he wasn’t the same person. He said that when we text he doesn’t feel the same spark that he used to, but when we are together it’s like nothing has changed. He says that he loves me and I still really love him. But I don’t know what to do. Someone please give me advice.
