is this guy afraid to lose me because he's insecure or because our communication is limited?

I'm seeing a guy for about a month now. we kissed once. we haven't had time to go out on any dates because our schedules conflict and he's more busier than me. I got frustrated & told him I don't think I can do this, well he called me & we talked but 1 of the things he said to me was "he didn't want to lose me to any other guy".i have given him no reason to say this but now i'm confused. he talks with so much confidence and doesn't show any signs of self esteem issues. but by his question, does he sound insecure? and btw...we have not had sex yet.
