Why all the drama?

I feel that I am not prone to drama. Seeing the drama of a co-worker’s romantic life brings a giant question mark over my head. If someone treats you poorly and you admit that it’s unacceptable, why would you return to that person? If you’ve invested considerable time, love, and effort into the relationship – I understand more. But if you’ve only been dating for a month, why all the drama? Are you really in love with the person at that point, or are you still on cloud nine? Sometimes I think my co-worker is a romance junky because she can’t stay single for more than a month at a time, and she lives in a small community where everyone knows each other and near every guy her age jumps at the opportunity to date her. She’s on Facebook and texting all day every day about personal things, and there’s some sort of romantic drama every day. Enlighten me, please.
