Is my guy friend a douche?

Marilyn

I'll try keep it short. So I dyed my hair blonde from brown and it was a big change to my appearance I got some compliments here and there. And I was not that self conscious about it. Then my guy friend keeps bothering me to meet up. And I agree, we go to place close by to play pool and everything is fine we having fun. He didn't comment much about my hair. Suddenly I tell him I started dating someone. He immediate says the same thing and that he is happy for me. But that's when he starts talking about how girls he's dated before are superficial and how he told one of them off. Just really mean stuff. That's when he starts making fun of my hair and that it looks really bad for like 15 min straight and just hands down being mean to me. I left right after that. Soooo why would he do something like that?
