What would you do if a guy...........?

This guy had said i was his girlfriend and kept hugging me(it was because e it was so hot outside and he needed some shade) but after a while he started to hold my hands andhe keep winking at me and when we came in from outside he kept being really nice tome like holding my stuff for me and when I came to talk to my friend that was next to him he pulled me down to sit with him so what you think about that? He's just a friend
