Don't depend on the word of a friend if your crush likes you he should be the one to tell you so act like you believe her but she wouldn't know she cant read his mind.
BE HONEST. It sucks,( for your friend) and it awkward for you but in the end it's better to tell your best friend. Maybe the crush has a friend for your besty
ask him if he still likes you and if he had a crush on her then why did is he your boyfriend he's probably trying to make you jelous
Umm.... I do not get the question but if what you re trying to say is "How do you ask some one out if his friend like you to" then you will have to choose and act like you do not know his friend likes you so if it turns out you do not like the guys you choose you can see still be friends with the other guys or even better ask his friend out.
Then that's a big problem... You have to ask the guy who HE likes better. ;) Cuz then it's fair
you ask your crush's best friend to ask your crush who your crush likes(it may not work but just try)
get with another lad to try and make your crush jealous if it doesn't work then he likes someone else or get a friend to ask him if he likes someone and if he does tell your friend to ask him who he likes. if he doesn't like you then move on you can find somebody better then him, somebody that actually loves you.
by the way your crush acts and looks around your friend
its because she is helping you make better friends or have a crush on you or likes you and maybe just like being around boys if so then that means shes trying to be around you if your sitting by your self or she likes seeing you laugh at yourslelf and being happy all the time but mostly likes you.
become his friend or move on and find somebody better
crush
You can ask the person directly that is your crush. If he likes the other person then you can't do much about it.
if there is a chance of your friend being with their crush back off if there is not or only a small chance or their crush likes you then tell your friend i told my best friend she was fine with it i mean its only a crush its not like they are actually dating
