Why? so you can feel good about yourself? Why dont you feel good about yourself already? figure that out first.
@billtx49 is dead on the money - you'll never be able to change anyone, female or male. You are going to waste a LOT of time dating sub standard people if you dont realize that.
Have you ever taken the time to really figure out what YOU want in a female? Intelligence? Financially secure? Witty? Demure? Respectful? Caring? Giving? Loving? Cuddler? High sex drive?
How about you sit down, figure out what you are looking for, figure out what kind of behavior you are willing to accept, develop some firm standards and stick to them?
You can start with rule number 1 - "I cannot save or change anyone. If she is in distress, I walk immediately"
Do not buy into the theory of scarcity and worry that if you dont snatch this (victim) female you might not find another one. There are plenty of females out there.
I subscribe to a law about the universe - the universe gives you the same situations and problems, over and over again, until your finally learn your lesson and do things the 'right' way. If you see the same pattern over and over in your life, it's because you haven't learned your lesson. Once you learn your lesson, you will not be presented with those same issues ever again (unless you start slipping) You will receive the next lesson, but the good news is that you are leveling up.
Get yourself some serious boundaries and standards and knock this $hit off
