Why'd it take him so long?

My boyfriend and I have been together for over 4 months. The only time he's ever complimented me was before we got together, he said I was "cute as hell". He's always talking about how pretty or beautiful certain celebrities are, which really upsets me because he never compliments me. He picks on me because I am pale (I have Irish in me, I don't tan..I'm not even that pale) or my height (I'm pretty short) or stupid stuff like that. Today, our friend said my profile pic on Facebook was pretty and he was like "pshhh". Later, I texted him "Can I ask you a silly question?" and he said "What?" I asked "Do you think I'm pretty?" He said "Yeah, why?" I said "You never tell me so." and he didn't reply. Why did it take him so long to tell me I was pretty and he never actually said it, just said yes when I asked if I was?
