Like you said fancy, which means you have not made your intention known to him. And since you not officially declared your intention, His attention is fixed somewhere. You cannot do anything until you make known your intention
Don't worry! Today I just found out the boy I fancy, fancies someone else. First of all, I was really sad. Then I got mad at the girl because all the boys fancy her. Then I started to cry, but my mother said, "Don't worry you will find someone else!" She also said that when I am older I will be pretty and that girl will be ugly. Even though I am pretty now, I will be even prettier! So if the boy you fancy, fancies someone else, don't worry because in a couple of years he will probably fancy you! (So will all the other boys and they won't fancy the girl)
The only way your going to know if this guy likes you is ask him.
Leave him alone and back off. He likes someone else.
Ask her straight out
When he has a penis.
Have someone else do it for you.
I think the best way is to just tell them, because they might fancy you back and usually, people like to hear someone likes them
Lie to the person you love and say the other person has done something horrid. Then the person you love might break up with them and be your girl/boy freind instead to thank you for telling them.
It means he wants someone else but is flirting with you as a second resort if the person he likes doesnt like him back
tell them to get over you and date someone else.
Don't waste your time hun, it seems like he's only messing you about. If he likes someone else, then he likes someone else. Surely you can do better than him anyway :) Good luck
Ask her.
