Why do guys act interested in real life, but distant when not together?

Anonymous
I have been seeing this guy and off for 3 months.. when we hang out, I either stay at his all weekend and then last time i saw him he invited me to his friends house party. I got along with his friends really well, one of his friends invited me to his wedding? This guy and I haven’t even had a discussion of what we arez
Although, when ever I ask him to hang out, he doesn’t give me an answer. It’s like I have to work around him! Is he just using me for sex? Why does it feel like he’s only available when he wants! I also hardly hear from him when we aren’t together. i can’t comprehend what he is feeling or doing to me, I am so confused because when we are together, he acts like my boyfriend. He even said I should move in with him!(wasn’t sure if he was being serious or not as we have only been sleeping together for 3 months) Help. Do I drop this guy?
