make sure it isn't serious.
although i am not quite sure what u r saying i believe u cant make someone be a boyfriend or girlfriend but lets say a girl has a crush on someone. if she wants him that bad he might try to get to know this guy or impress him in any way possible after the guy falls for her they become girlfriend and boyfriend
I would say don't flirt with him or the girlfriend will get jealous, wait until they breakup and then see what happens. Just make sure he isn't a jerk, if he tries to cheat on his girlfriend then you should just leave and forget about him.
you hog-tie her.
You could ask questions about the fake girlfriend to get some info or forget about he's not worth your time or effort if he has to make up a fake girlfriend.
I'd imagine in attempt to make you jealous.
you cant make sure - if your girlfriend feels that you are too suspicious, jealous or controlling, it might cause her to leave you in the first place.
A boy can have crush on you if you become close. Talking random stuff, going on dates can make him fall for you.
make them smile as much as possible. :D

If she is your EX girlfriend, the she is nothing to do with you any more, do as she asks LEAVE HER ALONE to make a new life without you.
NO. It would just make things difficult. Wait till they break up.
