WHY DO WOMEN GIVE MEN THREE TRIES TO GET THE DATING RIGHT?

I started dating a woman a few months ago, she broke up with her boyfriend for the second time 6 months prior to me dating her. She said that there was no way they would ever get back together but two months after I began dating her she dumped me and went back to her old boyfriend for the third time. Why does this happen?

Because women are crazy. She could have got tired of him when she started dating you,then after dating you for a while she started to missing him. You do know that they had to been communicating and possibly seeing each other while you and her were dating in order for them to rekindle their love?

Basically it happened because she doesn't know what she wants.

Maybe the woman in question has only been exposed to 'bad' dates and jumps to the conclusion all are the same.
