Why didn't he touch me when he normally does?

I'm seeing this guy, we are not a couple, but we have . Every time he came to see me in the past, we did it and every time I've come to see him, we did it. Although we are cool, is something we both look forward to when we make plans to see one another. So, lately he says he's been dealing with a lot and I haven't seen him in a a few weeks. He tells me he misses me and wants to see me. So he comes over. I was so horny and he told me he was too, but by the time he got there he was really sleepy so we just did oral and went to sleep. He ended up staying at my house for a week and I was expecting to have EVERY NIGHT. The first few nights he didn't even touch me when normally his hands are all over me. I even brought it up to him and he said that he thinks that's all I want is . I don't believe that's what it is HE LOVES . Then I even gave him oral to entice him and he just turned over and went to sleep after without even touching me! What's his deal? Why the new behavior?
