Am I losing him?. :(

About a week ago my boyfriend went off to work for a week in Montana, and me being the stressed out anxiety filled person decided to send him a long ass message; pretty much asking why he's with me but telling him that he means the world to me and I don't want to lose him. This past week, the lovey Dovey hugs and kisses have gone down to a minimal and he doesn't even talk or cuddle with me anymore. Yet, when he leaves for work, he kisses me and will then text me he loves me. I'm so worried he's just gonna end things and that I would have to move out. What do I do? Am I just over thinking things? Is he fine? Do I confront him?
