One very true lesson I've learned over the years about dating and men: most men prefer to chase and pursue, and they prefer a woman who is harder to get. That makes the chase all the more exciting to them, and then when they finally do catch you, they tend to value you and appreciate you that much more... especially if you don't give them sex right away too. If you make it easy for them, sure, they will take it for granted and they will take you for granted. Too easy. Then they also will think you're more desperate. But the woman who doesn't act desperate and chase? That's the one they want. Not that you act desperate, I do not know. I am just using that as an example. Just do the opposite of what you've done so far. Be the opposite gal, like opposite George in Seinfeld!
