How can I make my boyfriend feel like I do love him again?

Me and my boyfriend have been going out for a long time but recently we went through a rocky stage which lasted for like a day and then ever since ( about a week later )I've been trying me hardest be nothing but nice to him. Although the other night when he slept round he didn't want to snuggle or anything like he usually does and just went to sleep and when he woke up he made little effort in making it seem like he was fine and then got up, got dressed and at the door he said "I feel like somethings different between us" and I do feel it too but not to the extent that we should brake up over it - I love him just as I did before and I guess I've been acting differently to try and make him feel like everything is fine because it really is and if he would just commit more then maybe he would feel the same. Is he going to break up with me or want to? what should I do to make him feel better? I'm really struggling to do anything I can't take my mind off him and I don't want to go anywhere, see anyone but go to his house, see him and talk things out and I just need to feel like he loves me again. Please help me.
