My ex tried to contact me

My ex and I broke up because he had a terrible tendency of taking off and stonewalling me for weeks any time the conversation became the slightest bit uncomfortable.

He could not take constructive criticism, hence he could never hear what needs of mine he wasnt meeting. Any time I expressed a want he took it as a personal attack that he wasn't up to par no matter how gentle I made the suggestion. He never displayed enough stability/want of me to actually work on building up our relationship - he would not move it to a deeper level. Worse - he wouldn't do it for his own goals, or for his family. He essentially begrudgingly worked a 9-5, then sat home smoking pot and playing video games after. He was an eternal child, no chivalry - he earned the bare minimum and so he could never afford to be giving. The few times he did get extra he would spend it on weed or a car. I was such a pick me - I loved him and hoped I could teach him a better way to be in this world. All he did was drain me and emotionally hurt me after wasting years of my life. (I didn't know he would be like this, of course, he misrepresented himself and the mask didn't slip until I had moved in and was in love.) I grew tired of being broke from paying his bills, tired of not working towards a better future, tired of constantly grieving the loss of a relationship only for him to come back a few weeks later like nothing happened...

He tried to contact me recently, he wants me back. When I wasn't receptive he went on a rant using lots of red pill-esque buzz words like "wall". He accused me of being material, too judgmental, non supportive, etc Anything but recognize that it was HIS behavior which ultimately drove me away.

I didn't even tell him the above, because I realize that he has narcissistic tendencies, he is hyper defensive and honest feedback would do nothing but make him mad and run off again. He will never recognize how he creates his own problems, he is too self absorbed to be honest or empathetic. It hurts me... I have moved on with my life and have a great scrotation, but the fact that he is unable to withstand open dialogue still has me profoundly sad. I lost too many years on a stubborn, egotisical fool. I know he will go out there and date - and ruin another girl's life. He will never get the therapy he needs. I'm left contemplating how the manosphere thinks its providing support but in reality they are only helping the personality disordered males to dig in their heels - never able to obtain happiness or evolve into real men. If they really wanted to help men they would preach empathy, responsibility, work ethic, loyalty and life building, instead of instilling narcissistic qualities which in the end ultimately harm their readers more than anyone. I will move on and build a better life - he will die alone... I feel pity for him, a pity no one in his manosphere is capable of feeling...
