Im seeing a lot of good stuff going on here, and a little bad stuff.
Basically, you get these hot girls numbers, and they have boyfriends. WHO GIVES A ****! Don't just delete them from you're phone and not talk to them. That makes you like EVERY other guy out there. Are we every other guy? No.
Does that mean you have to try to seduce them? Not yet.
One of two things will happen. They will break up with their boyfriend and you will be there.
But more likely, they will hook YOU UP! Hot girls have hot friends, and get into the hottest parties.
I have a **** ton of friends who are females, because I'm a social creature. I literally care about them, because I love meeting people. I met this girl last semester and rreally liked her, it didnt work out, so I said **** it she's super cool so lets be friends. I started pursuing other women and we are super tight now, and in return I'm now hanging out and gaming all her hot friends.
So just because they have a bf doesn't mean you should delete it and move on. Be that guy who is the life of the party, who wants to meet EVERYONE and is the center of attention. The guy who Hot girls want to be around, and who hangs around with the hottest women. Socially proof yourself, gentleman.
