Flicker,
Welcome! You've come to the right place. Having recently survived a painful and vitriolic breakup with my ex-N, I can truly relate to your feelings of emptiness.
As one poster on this board put it a while ago, an N views people and relationships like milk cartons - once emptied and of no use Ns move on quickly - and with little regard for you, your feelings or needs (which isn't too dissimilar to how we were treated during the relationship, mind you).
The first and best thing I can share is to ABSOLUTELY CUT CONTACT. View your ex-N as toxic poison; an emotional vampire. I had trouble doing this at first because I didn't want to villify my ex-N. Afterall, he was someone I loved, cherished and wanted to spend the rest of my life with...how could things turn so ugly so fast? EASILY - you will soon witness and experience the
true person underneath the veneer. Unfortunately, I've found the traits/characteristics we loved about our Ns were just a fascade to cover the barren souls that they truly are.
Next thing I'd recommend: if you've ever considered therapy, now is the time to look into it. The confusion, pain, disappointment and disillusionment of ending a relationship are difficult enough but with an N it's all the more so. They have toyed with our emotions, used us, manipulated situations to make it seem our fault, lied, cheated and spread rumors to family, friends and mutual contacts. Having someone help you sort this out will be crucial in your healing process. At the very least, check out some of the books recommended on this board. They're invaluable and will help validate your experience in loving and/or breaking up with an N.
Last, ally yourself with only supportive friends or family members. During my break-up I discovered who my true friends were. You need unconditional love, support and understanding right now. If anyone thinks it's time to criticize, ridicule, judge or express disbelief in your situation (i.e., how could you allow him to do this, that and the other) then distance yourself from those folks, pronto. If they haven't experienced life with an N, they'll have no clue what you're going through right now. This is not, I repeat, NOT a routine end to a typical relationship.
I was interested in your statement:
I walked out on him and we never really ended the relationship.
This is typical of Ns. There will be little to no closure. They're too busy trying to latch onto their next source of N-supply. Don't expect there to be any well-wishing or fond memorializing of what was. You are and were an object to your N. Now that you've lost your usefulness, you're as easy to discard as a piece of Kleenex.
I feel for you, Flicker, and hope you'll keep us posted on how you're doing. Take care and be gentle with yourself during this challenging time.
Best,
bludie
