I am a girl myself but I am going to look at this as if I am a boy. I'd look for other girls. There are so many other fish in the sea, my friend.
she is in love with someone else and you cannot have her
she flirts
yes
If that girl isn't your friend then you don't need to feel guilty he is yours and enjoy that just because someone else likes someone you have and that likes you back doesn't mean you give up your boyfriend/girlfriend...... just ignore it
Look for someone else, tell her how you feel for closesure.
Not really sure what the crush is, a crush soda or a crush on someone. But, maybe she was embarrassed about something and her mom was close by made her feel uncomfortable.
step up your game to show him what type of girl he wants to be interested in.....my opinion
Normally it suggests that she has a crush on that person. It may be something else but that's unlikely.
He has a crush on this Girl named Hailey
look for the mean character about your crush. Sure when his your crush you think his/her is all sweet and stuff but nobody's perfect so start looking for the mean things the guy/girl would do and hate him for that.
If they are in love with another girl then you should leave it alone completely. Eventually you'll find someone who is not involved with someone else and you don't hurt anyone, including yourself.
I say you should ask your crush out since the other person is a jerk
