Do you think this guy likes me? he's showing mixed signals?

So he would copy me, I never see him wearing blue, but when I started wearing blue, he now wears it all the time. I told him my dad has an Audi, and he bought an audi after selling his car. He gets jealous when guys stare at me, like this guy looked at me and he kept asking if he knew me. He also gets jealous quite often. I have a feeling he's using me for sex though cuz he used to text me all the time during the day and now he only texts at night and i complained to him and things hasn't changed. He did say he's busy during the day. He used to text me all the time and now not so much. we did kind of established a relationship
