How is it that despite OJ Simpson's past and his pattern of behavior that he can still finds girlfriends?

Men like OJ are good manipulators and can convince vulnerable women that they are innocent. Women are too trusting and tend to believe words rather than past behavior. If you notice, he picks women who are younger and easier to convince. Con artists use the same strategy. And of course there are always women who are looking for "bad boys" because they think they are more macho, instead of realizing the danger and risk. By the time they smarten up, it's too late and their own spirit has been broken. They just don't understand that real men don't hit women or disrespect them. There are many other reasons too numerous to mention.
