meeting with onities after 6 months

Guys, I want to know your opinion.

In a couple of days I will after a half year meet my onities, we (group of poeple) are going out play bowling. She will ne there with her boyfriend (theyre a couple for 7-8 months and he isa total AFC)

I want to show her that she did a mistake, if she is with him. Any advices?

If she has ANY clue that you like her, or there is ANY possibility that she ever considered you as an option, or was interested. Just be the most interesting guy in the world, and flirt up a storm with the other ladies. If all the other girls are into you, she might think what you want her to think. Doesn't mean you have a chance though.

If she has NO CLUE you're into her, or there was never any stated or understated attraction. You have very little hope. Move on.

I think she will be pretty aware of what you're up to if you pull the "be charming with other ladies to prove her something" and come off bad.

Instead, have the fun of your life with the entire group, not just with the chicks. Actually spend more time with the guys than with the chicks. And with the little time you spend with the chick, make the best of it and make them think you're the bomb. Even better, if both the guys and the chicks think you're the man, then you're in a great position.

Be the leader of the group. Don't make it seem like "she made a mistake", make it seem like "I'm the king of the world".
