Romance vs lust

My boyfriend tells me he loves me and misses me but sometimes I wonder what he means. He'll say things like he misses me but then start talking about how he misses feeling on my ass. Or he can't wait to drill me. I don't know if that's his way of flirting with me and keeping things spicy but it makes me feel cheap. We haven't seen each other in a week and I wanted to hear something like I miss holding you or being around you or I miss your smile. I heard Nothing romantic, Instead it was all sexual. Yesterday we got drunk and high then had sex but afterwards, I fell asleep and he left. I just wanted him to stay with me since he was talking about how much he missed me and couldn't go another day without seeing me. I acted like I didn't care he was leaving because I didn't want to make a big deal of it and get into an argument. We've been together for 3 yrs and at first I didn't mind as much but now I'm starting to wonder if this is normal. I feel like I'm just a sex toy. Even though he swears I'm not. But he won't be romantic with me ?? Am I looking to deep into this ?? Am I asking for too much ??
