I've known this gril for like nearly 5 years now but we have just started becoming reely good mates recently. And I've started 2 like her but I don't no if she likes me back. I've been 2 hers on my own a few times and we went out on my birthday together. And now we are going to the cinema together this week but I don't no if she just wants to be friends.

Its reely confusin for me because like she's my best mate who's a girl and I think I'm her best mate who's a boy but how far does she want 2 take it. I've been ponderin asking her out 4 months now but I suddenly think does she reely like me. N 2 top it all off she's my teachers daughter. So should I ask her 2 go out with me or not?

Does she show any physical affection when you guys go out together? Are you paying for both of you on any of these outings? Do they feel like dates or just hanging out with a friend is what I'm trying to get at...

Yes, you should ask her to go out to a specific thing on a specific day.
