how they devalue after discard

I am 9 months out and share a child with narc. I immediately went no contact, only texts regarding our child and pictures. i remember in the early days of no contact/ limited contact i longed for a simple text of "are you okay" "i miss you" etc. i never sent him one, and it took alot of strength. later on on the occasions i would have to text him ( only about child) he would text back with one word answers , the worst being the letter "K", for okay. it infuriates me because when we were married and texting each other he didn't do stuff like that. my point ( and i do have one) is that there little short one or two word texts such as "k" "lol", are meant to devalue us after the fact, to show us that our concerns/whatever have no meaning. yes, i made the mistake of texting him once and admonishing him for being a lying jerk and i wish i hadn't. but it was only one time and it was over christmas and i quickly recovered. now, i must say that i MIRROR him now on the unpleasant occassions i have to hear from him. and now that he "gets" that he is being ignored i get occassional hoovers like today, he knew i was out of the country and when i reached miami he had texted 4 times even though he knew the dates i was gone. i ignored every one of them and only when i got my luggage for a 5 hour layover in miami did i text back " im in miami". don't be hurt by there textbook narc replies. and first of all, if you donn;t have a child or children you should be completely no contact. for those of us who share kids it can be hard. just my 2 cents.
