What is it about a woman that makes her special to a guy, for the long-term?

i will tell you what i always tell my friends. you have to set standards and find out what your looking for. don't go out to the game and just look for physical attraction. you have to ask yourself what do i really need and what are there and my strong points. when you find out those strong points compare them and see if you honestly need this woman. by going out with these fast woman who you think are looking for a long term relationship, your just bringing down your self-esteem towards finding a lover for life
