I will type this out twice.
There is nothing wrong with a girl dating more than one guy!
There is nothing wrong with a girl dating more than one guy!
More than half of the members of this forum date more than one girl at a time. Or, at least, would like to.
The reason this girl is dating all these different cats is not because she wants to give them booty and stick you with the price of a meal. It is because she recognizes, as should you, that everybody is different. Every guy brings something different to the table. Just the same as each girl I meet has something about her that makes her more special than her friends.
Why does this bother you, her seeing other men? Why would you assume that she likes them more than you? Have you lost your way from the path so quickly?
You are in control of your life, are you not? You decide how you feel. You can choose to be happy or you can just let life's little details eat you up.
I'll break it down for you.
She did date you. She found something about you attractive, or at least, worth checking out.
She is honest. How else would you know about the other fellows?
She may have told you to let you know that you will have to be smarter and more disciplined than the other fellows. I'd rather know she's seeing other guys, than find out later down the road. It wouldn't change my actions, because I'm going to be consistent.
In many ways, consistency = honesty. I don't pretend to be busy teaching 4th graders the En Passant move in chess. I don't pretend to spend 20 hours a week teaching battered women basic computer skills. I don't pretend to build a fence around my house, I do these things because they make my life better, ergo, they make me better. Thus, my standards raise.
You can't just steal lines and tactics from this site and expect the ladies to just follow you where ever you may go. You have to actually be the man, not just pretend while she's around.
You wait a certain number of days before calling to train yourself to not be dependant on hearing her voice. You do not need her to be happy.
You will pick your activity, something that you enjoy doing. You will invite her along for a specific time. She may already have plans. If her interest level is high, she may offer a different night.
You can counter with a different night, or simply tell her that you don't want to go that far up the calendar. Wish her a good weekend and let her think about your interest level.
You are the great catch, remember?
No offense to you. I just like to think that if we're as special, and awesome as Pook says we are...we would choose a term different than a huge, slimey fish CAUGHT in a net.
