Dude, i empathize but you're asking the wrong questions.
First if all, that cunt did you a huge favor. You might not see it right now but trust me, you will someday. And as painful as it is now, it would have been infinitely more painful in the future. It's a blessing that you found out now. It really is. So don't do something stupid like try to win her back. She's not worth it and I guarantee that you'll never be happy.
Secondly, and this has more to do with your question about trying to figure out what makes men appealing to women. The question is boring. Flash some money around, throw in a little sweet talk, and you can fuck the most beautiful women anywhere. It's really that simple. That's why chasing numbers is so meaningless. Your "conquests" are essentially worthless unless you're only interested in variety, which some men are.
The question you should be asking is what do you as a man find to be appealing qualities in women. Rather than trying to figure out how to make yourself more attractive to women in order to impress them, make those bitches impress you. Make them show you why you should let them into your life. What can they offer you besides pussy? How can they make your life better? What can they offer you that you don't already have? Will they be supportive of your dreams? Will they be a good mother to your children? Ask those questions and 99% of the time the answer will be that they provide absolutely no benefit to you.
Men have been conditioned to believe it's us that has to impress the female. It's bullshit. Women are mostly a liability to us no matter how you look at it - that's why they used to come with a dowry. So they damn well better bring more to the table than a good fuck because you can get that anywhere.
Know your worth, dude. Then make those bitches prove theirs. You might just find that one-in-a-million that really blows your hair back.
