I am currently dating someone at the moment and there's a guy in our friend group that I used to have a crush on. Anyway, since getting with my bf, the other guy has been acting strange. First thing, he offered a sweet to everyone as he didn't want it. No one else wanted it, so I said I'll have it. I went to take it and he swerved his hand around mine and stopped near my mouth. I was weirded out by it but also felt nervous. Maybe I still had feelings for him, but I don't know. Without thinking i bit into it from his hand. That was the first weird moment.The next thing that happens, is he made fun of me crouching down at college. My bf said something at the time and I became flustered. So, i did what i always did and pinched/punched him in a joking manner. Next thing I knew, he grabbed both my wrists and put them over my head. He then proceeded to push me gently and kept eye contact with me. I'd be lying if I said that it didn't make my heart race, but it also made me confused. He stopped and stood in the position for a bit and then let go without saying anything. Bearing in mind that my bf is in the same room, but isn't paying attention to anything happening. Later in the day, my friend decided to see who I was compatible with. I got the guy and she did him. He got me in the end and when the group found out. Our other friend said "he wants you anyway". It's possible that it's just a joke. However, they never joked like this while in previous relationships. Another thing that happened, is the guy said I could keep his pen. He never does that though, and he used to always ask for the pen back because he could only write with those really nice inked pens. I just need some much needed advice on if he likes me, how I deal with it and do i tell my bf.
