Swinging through life

Ive been in a relationship for well over a year. And hes amazing to me, hes always treated me right and he loves me more than ive seen anybody love a stupid girl.So why am i still in love with my abusive ex? I dont understand it anymore. Im the one who left him, so why am i upset that his new girlfriend hates me?Why are females so stupid. Why are females so sensitive and weak when it comes to the opposite sex?
