How do I get him to ask me if I want to hang out instead of me always seeing if he is free?

I am have been talking to a guy for a while now. At first it was him and I taking equal turns with asking each other to hang. He went away for a job for 4 months then came back. Now since he has gotten back it seems like I am the only one asking if he is free and wants to hang out vs him asking him. Yes, his roommate did move back and he just started a new job but it's starting to bother me. How do I get him to ask me instead of me always asking him?
