How do you help your man?

Hey there! So me and my man are having such a hard time in our relationship. His mother is so controlling and its made things so difficult for our relationship. I'm afraid I'm going to lose him. We have never had a normal relationship. Well we broke up for a bit and are back together but ever since then he has been more cold and short when we text. I give him space but he doesn't like it. We can't hardly see each other because of his mother and he has 2 sports he plays which takes up a lot of his time. He's gotten very active in trying to improve his body. I'm not sure if he wasn't to be together. Its hard to get him to open up. I'm always worried about him. What do I do? Should I do something special for him or just give him space? I'm so confused. Please help
