I realy appreciate that the main point approached in the article is about self knowledge and self-worth in order to be someone similar with whom you would like to relate. But i guess the first point is: do you realy want to have a long term relationship? So many people thing only this kind of relationship will make they happy. There is no problem to have less lasting relationships. Sometimes it fits better with your life style!
I have also written about that subject (and probably even linked to those articles in the above piece). You should read more of my stuff, because I’ve definitely touched (multiple times) on the subject of not being made for or prepared for a monogamous, or committed relationship.
