Y'know...funny enough, my friend dates this female who is nothing but trouble. He got into a brawl at a bowling alley because she started some foolishness with a couple of guys by flapping her gums. She puts dude through hell, and I've lost count on how many times this guy has complained about her & moped around depressed and angry. On the flip side, he has a chick yearning for him, who, for the most part, has her mind right. She wants to give dude the world. Cooks, cleans, offers to do his essays and homework, gives him rides..basically holds him down. When asked why he won't leave his hectic relationship, this negro replies that it's because he loves her and he knows she's no good, but he can't go anywhere.
Both of these females are equally unappealing physically.
For whatever reason, people like the drama. A lot of women will actually complain if there's nothing going sour in the relationship, and a lot of men happily feed into it under the guise that they hate it. I admit, I've fooled around with my share of females that I knew were bad for my health. Animal print, tramp stamps, clear heels - the whole nine.
However, I never held a relationship with one, and could never fathom conceiving a child with one. Every chick I've dated seriously was a 'good' girl.
I think folks just enjoy the dark side of human nature and are attracted to it in a mate. It's alluring to most, whether or not they admit it.
