I'm literally chocking up ! 


Ex and I had a huge argument over the phone. But to give a back story, we had DS very young.. I was 16 he was 17. EX dp was very abusive. I assume he would change because his young and has time to grow... he hasn't and he is now 25 years old.
Ex has had sporadic contact with DS, doesn't support him financially, emotionally. We had a huge argument because we last heard contact from him in April and previously before we didn't hear from him from November to March. He, obviously, hasn't seen DS between those dates.
I was angry with him because I was getting on with my life and so was DS and now his making contact again, popping up like a genie, I told him that " it's not fair on DS and I !"... he replied he didn't make contact with us because " I was being stupid with my dumb comments and he was working...". He then was pressuring me to come to his to have sex and of course I said " No fucking way". He then got agitated and angry and some comments later he said " You forced me to be a dad to DS when I wasn't ready. His disabled ( DS has Autism) because he wasn't ready to be in this world and because of the age I had him...so it's my fault and I should burn with my decision...burn". I was shocked and replied "burn... DS should burn" then he said "No, it's not even about DS...". I just hanged up and blocked him.
I'm so upset. Does DS have autism because of the age I had him? 

is it my fault ? DS is doing so much better, his cheeky and so lovely (though can be a handful).. I pay additional private therapy lessons to help DS even more and he goes to a specialist school (which I had to go to court for) and has thrived there. Am I not doing enough ? Did I cause my DS to have Autism. How can the ex blame me, he kept pressuring me to have sex with him when we were younger (like his currently doing). I wasn't ready but he kept on pounding it into my head for 8 months :(((. I'm just so upset.
