How do you get a guy to chase you?

There’s this guy I have this crush on who I haven’t known long. The other night at this party we spent the whole night together talking, with some flirting. I got away with his jumper which he gladly gave to me and We had been talking a bit after the party. We were at another party together last night and every time we walked by another he would say jumper with a smile to me. It wasn’t till the end of the night we got into proper conversation and I gave him his jumper back which I had brought to the party with me, but I somehow managed to get it back off him. He said to me after that he’d have to see me soon to get it back off him. We were talking a bit today but not for long and he hasn’t replied to the last thing I said.I’m getting complete mixed signals and don’t know how to act. Its not as if the guy isn’t interested cause as I said I get signals that he is, he’s just quite the ladies man and not entirely focused on one I can only guess. How do I get this guy to really chase me?
