At risk of over-generalizing, I think that's exactly what many single women lack: PERSONAL STRENGTH. Me included, obviously. Otherwise I wouldn't be in this self-induced, self-help bubble. Lesson learned because, without personal strength, we tend to pick partners and/or relationships that painfully illustrate just how personally weak we are. And not to make excuses for us single ladies, but we are struggling against this culturally instilled preoccupation with finding "the one" without any emphasis on finding ourselves first.
I had come to terms with the fact that I was damaged goods and carrying far too much emotional baggage to even begin contemplating a healthy new relationship that wouldn't turn into repeat episodes of relationships past. If I really wanted to be happy and if I ever wanted to experience lasting love, I'd have to rebuild myself from the ground up. I needed to fix the cracks in my foundation, gut and re-build my interior while maintaining the basic structure of who I was.
