Is my ex's friend flirting with me or being friendly?

Anonymous
So yea I went to hang out with some friends and a guy was there who's a rather new friend and I don't know him that well. Well I was sitting next to him and he touched my shoulder/arm a few times while talking when he really didn't need to. Our legs brushed against each other multiple times too, he apologized for it but then it kept happening. And I felt like he was talking about me a lot? Like he would steer the conversation to mention me or make fun of me somehow.

The next time we all hung out, this time when he greeted me he hugged me, which he had never done before. After the hug he tracked me down to ask what perfume I was wearing. He asked me about the perfume again then made up a silly song about how I always smell nice. That day I also wore my hair down (it's usually up) and he told me it looked nice. He called my friend later to ask about the perfume again too, and he apparently said something he didn't want me to know.

We hung out again in a smaller group of friends. This time, he touched my arm and shoulder again unnecessarily while he was talking. Then at one point we were reaching for the same thing and our hands touched by accident, so I pulled back and said sorry and so did he (it was so awkward). He also teased me about liking Ariana Grande, the fact that I'm a Scorpio (said I'm toxic), and he called me good weird. He also asks me a lot of questions. Like he's writing a book and wanted my opinion on things, but he don't ask anyone else in the room. So, I'm into marvel right? We were all looking at a 3D model of the ship from guardians of the Galaxy online, and he *randomly* offered to print me a 3D model of the ship because I was wearing a GotG tshirt (I also had a nip slip in this shirt).

It doesn't make sense why he'd be interested in me. I say this because he's about 10yrs older than me, and good friends with my ex. I feel bad even entertaining the idea. Opinions?
