Is there a woman out there who's never been duped or dumped by a guy? Or has been in a relationship that just didn't work out in the end? Yeah, I thought so.
Everyone gets hurt at one point or another. I don't believe that one person can feel more hurt or get more affected than the other. Betrayal, failure or rejection hits everyone just as hard. The only difference is how we deal with it. Some, after all the excessive crying, drinking, wallowing, shopping and eating is done, wake up one morning and make the decision to get on with life.
But some carry around all their baggage, even after they've said that they've moved on, acting like the perpetual victim... good gawd! Playing the damned damsel in distress is cute for a while and it helps inflate a guy's ego. But honey, after a couple of months, it just isn't fun anymore. Whether you do it consciously or subconsciously (a little introspection might help!), stop using your battle scars as a way to try and guilt the poor bastard into not leaving you.
Stop looking for someone to save you. Save yourself.
