Why is the girls boyfriend acting weird?

I’m somewhat friends with this one girl, she talks to me a lot and I make her laugh a ton. Her boyfriend is someone I’m not exactly friends with but he acts weird regarding me. He started wearing the same chain as me for one. Another time he thought I did something I didn’t do and told a ton of people it was me and then complimented me on it and I had to tell him I didn’t do it. I once made a joke and he approached me like an hour later to tell me he thought it was funny. He also once made a joke that I didn’t really understand and then like three days later he came up to me to try to explain the joke.

What the fuck is going on with this dude he’s kissing my ass like crazy. I appreciate havin fans but it’s getting weird
