Time.

Is it too much of me to demand time from the man i am seeing/ dating? He's always busy at work. And if he's not, he's busy taking a rest. He doesnt have time for me and i want more attention. Is that wrong? 
Ps. We are not official or anything. Im starting to think that maybe he doesnt want to make it so because of this. Or he's not just really into me. :(
