What to do with the sweatshirt of a hook up?

A few weeks back at a party I met this guy who seemed really into me. A week later we ended hooking up twice that weekend after parties. He gave me his sweatshirt when I took an Uber home.

He’s sending a lot of mix signals where he never reaches out to me but at parties is all over me. Im assuming I’m a possible hook up only at parties, which I guess I’m fine with even though I would be down for hooking up outside of that.

So since I was usually the one to reach out to him, I decided to let him contact me first which I don’t know if that’ll happen. I still have his sweatshirt and I want to message him on a weekend to go and give it back to him (possible hook up again lol) but like I said I wanted to see if he would reach out first.

What do you think?
