Hi, Adhesion...Hunny, you've had a very bad relationship experience. Whether it is accurate to label him a "sociopath," I'm not sure. He sounds very selfish and self-absorbed, and lacking moral fiber. I've been there, and I do know that recovery from such experiences brings forth such labels as "sociopath" and "narcissist." Also, it takes a lot of time...for me, it was years...to get some perspective on WHY I allowed myself to involved with such a character. When you begin to acknowledge to yourself that, while being a victim, you were also a participant in the dysfunction of the whole thing, you'll be able to let it go. First, it means healing yourself, whether you do this thru therapy, self-study, or just giving yourself lots of time. In my case, because I'm older, had had lots of past therapy, I just removed myself from the dating scene, did lots of reading and introspection. I did not want to repeat this mistake again (as I had more than one such experience like this). When you come reeling out of such a thing, my humble opinion is that is advisable to abstain from dating for a time (what amount of time is up to you), during which you regain yourself, your sense of self-worth, and ability to discern. Discernment of what is good and bad in potential partners is key in future healthy relationships.
