Tales of mistreatment, tales of domestic abuse, heartache, infidelity. The one common thread that always sticks out is that they are not going to put up with it anymore. They always speak of how fed up they are with that person, or how they are leaving and ending the relationship and moving on. I usually just listen and shake my head. Women are rarely strong when it comes to this department.
Men usually stick out bad relationships because of the sex.
Plus, once we find a woman who's willing to put up with us, rarely will we want to expend the effort on trying to trick another female into liking us. We only get one opportunity at life, and life is short, so do not waste precious time on a doomed relationship.
