Hi. I am 16. So i got off with a girl (she is 17 but in my year at school because her birthday is before mine. We are at different schools because mine is all boys and hers is all girls but they are really close) a couple of months back and started to like her but then she turned me down when i asked her out but we stayed friends and spoke regularly since we got off.

She also texts me stuff sometimes like 'you dirty thing' when we are flirting and she wishes me good luck in things i do all the time and then asks me how i did later and she also expresses sympathy a lot for me. Finally, tonight i saw her again with a group of friends. At one point my mate whos hose we were all at put some music on and he said i should dance (referring to some dancing i did at a party with a guy friend last week) but i said i wouldnt because i didnt have my partner (the guy friend). She then offered to dance with me and i warned her you wont like it (it is pretty dirty so that it is funny) and she said she had already seen it and didnt mind. My group of friends always make jokes about me and my guy friend i danced with being gay because we always pretend to be because they find it funny. Whenever i am talking to her and we joke about it she says something like 'i know your not gay '. We ended up talking together a lot and we got quite close a few times when we were throwing yoga balls around and we kind
