what if the ex N can't get a secundary supply...

I have been reading a lot about this,but i would like to know what happens to a cerebral narcissist that don't have a secundary supply anymore like my ex N ,that devalued and discarded the mother of his children with whom he lived for about 18 years and later he D&D me after 2 years,and is NC ....And i did broke NC and he told me he doesn't care if his children don't even like him anymore,and other people are also not of importance to him...we all gonna die anyway so doesn't matter to him if people like him or love him anyways....but he hopes that one day he is going to find someone that he can get along with,in a relationship or friendship...i offered him my friendship but he tells me he doesn't want anything to do with me anymore....(please reead my story)it seems like he is getting angrier...Has anyone something to tell me about this?He is 42 years old,has a very low salary,works as a maintenance man at the projects...Is this a sign of a depression maybe because he is having a hard time getting a good secundary supply ?I think when he dumped me he thought he could get something better, but to tell the truth,it doesn't seem that way....please ladies your opinions about this subject?Thanks
