Bf having space issues.. please help? Guy thing?

Here's is what he sent in an email.. an email..

Hi baby. It was a weird weekend for me. I think I was feeling like I had too much to do this weekend. I know it sounds crazy, but we are going to have to make ourselves take breaks from each other. Everyone needs some personal space. We both need to have time to get things done, whether it's homework, going to the gym, or just breathing. It is not healthy to spend every available moment together. This is the kind of thing that I don't talk about well in person because it comes out wrong when I'm thinking and talking at the same time. I think I was pushing away because I feel caged with commitments, in general. I don't want to blow up or isolate. I think I just need to feel like I can ask to have some time alone without having a guilt trip laid on me that I don't want to be with you or that i don't love you. I know we don't spend a lot of time together cause we don't have that much, but I still think we need some time alone.
