well if you LOVE him you should
Because a woman is attractive for men
she still flirts with because she is probably trying to make her boyfriend jealous... or get him back for something he did.
They were dating, but they aren't together anymore. They're still friends though.
start dating him. run up to him and give him a big kiss so he starts loving you instead or flirt hard out!!
Then wait. I kno it can be hard but still be friends with him. Just still be a really good gal friend to him and he might change his mind.
What happens is that he may continue to flirt for as long he he feels it suits him and may or may not change his mind on dating. Some just like the attention of flirting, but would rather not get into a real relationship.
Do it only if you are willing to ruin your friendship with your best friend. It's a rare friendship that will recover from invading someone's romantic territory. That said, if you are willing to do that, first make sure there is a really strong chance he feels the same way or you will lose both your potential lover AND your best friend.
they could be i don't know for sure though
He is probably just flirting with you or he wants to date you while dating your best friend. Your choice.
they were dating but not anymore. they are still very good friends though. Yes, they are engaged. Andrew posted it on his facebook.
you can
if they broke up with you, move on. If you broke up with them and they flirt with you, flirt with them back
