What do I do?!?!

Samantha
So my bf has been working and I haven't been able to see him except for on sundays, and I asked him if we would be able to see each other more then this and he said he didn't know. Then the next day I ask if he was ok and he said that he didn't know and that he was jut thinking about things, and he said I was one of them, I asked if it was bad and he didn't know....I asked if he was wanting to break up and he said not really, but I'm still so worried. And he won't tell me what's going on! What do I do?? Help please!!!
