I think you like to be abused by her.. The way I see it, no matter how good of a sex partner the girl is, when she doesn't RESPECT you, every thing cancel out. I know you treat her good, but the reality is, she has no obligation to return the same affection to you. Think of it this way.. when you invest a stock option. it continues to drop, no matter how much money you keep investing. Do you still continue to invest? Only a fool would do that, and I hope you are not one of the fools.
Bro, your pain will pass over time... Until then, try to spend time with friends and potentially visit Macau more often... Go out and have fun with other gals... You will eventually meet someone who will treat you right...
