Another thing I learned was from another wonderful book called "Meet And Keep The Right Man" is that there is a general common theme with women who have a lot of failed or short term relationship that many of us (me included) keep repeating over and over.
These are feelings of inadequacy and our fear that deep down, we're not good enough is called an "ineffective pattern of choice," which is sort of what I talked about before, but there's actually more to it.
The author of this book showed and proved to me that many chronically single women have a couple of things in common- underestimating themselves, feelings of isolation, and low self esteem.
When you have these things (deep down - I know now that I did) you set yourself up for self sabotage and for behaviors and relationship killers which can scare good, decent men away, and will doom your relationship every time.
