What Should I Do and does he like me? (guys and girls answer)?

I don't know what his friend could have said to him but whatever it was it doesn't matter. The guy was still dancing with you and if it really mattered to him he wouldn't still be talking to you. If it was something mean about you his friend said, then at least the guy stood up for you when he kicked him. Next time you see him I recommend that you talk to him and when you get deeper into a conversation just ask him what his friend said. However, if it was the guys friend who kicked the guy you fancy, he could have just been in a mood or he might have an issue with you. Either way don't get annoyed by guys friends, normally they aren't very nice, trust me, I know. I hope this helps you. Good Luck xx
