Was I being a "nice guy" here?

So I asked a girl at school I liked if she wanted to hang out sometime outside of school, and she said her parents are strict and wouldn't let her go out. Was I disappointed? Of course, but I said alright and we went about the rest of the day. Two weeks later, my friend who is friends with her showed me pictures of her insta and it was showing her at a local coffee shop with her new boyfriend. I got upset and gave my friend's phone back to him. I know she wasn't obligated to say yes to me, but I wish she would've been honest with me and said she wasn't interested. I commented on one of the pictures saying "Now your parents let you go out now?" Her and her friends were blasting me calling me a nice guy, pervert, creep, among other names. Then I replied to all that saying she lied about not being allowed to leave the house. Was I being a nice guy or not?
