Great advice in this thread.
There's definitely different types of women out their with different needs and wants. Some use their looks to their advantage inorder to "use" people. Some of these women know no other way. Some though, value themselves and save their energy for men of worth.
Rex's post makes a good point (didn't watch the videos). 99.99% of women will give you $hit tests soon into the relationship. That's just their way. They need to know the boundaries, and what kind of man you are. If you fail these $hit tests then some women will move on, and others will keep you around to use. However, if you pass them, then some will also move on, they see you as un-usable, so they have no need for you. And others will take it as a challenge, they will go into game mode....in order to win. A lot of these women are not looking for a healthy relationship, they are not healthy themselves. They cannot recognize a good partner.
Filters. It really boils down to what YOU are looking for. As women do with men, we can also do with women. Compartmentalize, categorize. I have women that I've known for a long time. I hear from them every once in a while, and vice versa. Am I banging my head on the wall, trying to get them all into bed? No, that would not be good for me. However, I can keep them at arms length, test the waters every now and then. Have they come around? Matured in some aspect? Changed their ways? Are they looking for something different than they were?
Emotional detachment. You will need to recognize when to the cut the rip chord, and when to invest your time and energy. Opportunity cost. Is this woman worth it? Can my time be better spent elsewhere?
