So I went trick or treating with a Pretty girl. She's hot all the guys like her an my best friends friends best friend is her so she came trick or treating with us. She wanted to talk with me all night and would wait for me while my friends went ahead does this mean she likes me or is it just her being nice
For those who are wondering this is a different girl the last one dumped me 6 weeks ago I'm abit anh about it. And if she did lime me and I asked her out would it bother my ex because she isn't datin anyone right now

Oh yeah and were both 13 and she is not in my class

'does this mean she likes me or is it just her being nice'

It means one of the below:
She likes you
She is just being nice
She is being nice, and also likes you
Nothing at all

We don't know any more than you do. In fact, you know more than we do, even though you are only 13. It takes years to learn how to figure out what other people are thinking, but there is a rule of thumb: be nice, friendly, complimenting, and curious about someone's interests and preferences, and they can't help but like you. You don't have to 'be' anything yourself.
It may not turn into romantic feelings, but it never hurts to have another friend, and who knows where that may lead? A change in feelings or a way to meet someone else...

What does your ex have to do with this? Why are you worried about what she thinks? If it bothers her are you not going to ask the girl out?

I think the girl may like you but I also think you both are pretty young and nowhere near ready to be dating. Whatever happen to friendship?
