If a woman goes for a guy who VISIBLY and obviously treats her like crap from day one, why would you ever give such a woman a second thought?
Some of us are kinda protective. Its hard to see a nice girl making mistakes and not want to help her. Women tend to be the last to know what women want. Ive had girls tell me what they did and didnt want but they then go for what they always go for, the jerk who is confident, its usually not a mistake the guy is both.
Most women dont become friends with guys to hurt them or use them, but people often do what they dont intend.
