Search Results: he blocked me on facebook

I asked him for some stuff for our child on July 6th 2020 on Facebook via messages and my ex blocked me. On July 9th 2020 his very close friend popped up on my "people you may know" which is strange because I'm blocked by my ex and him and his friends live two hours away from me and I don't know them. His friends never popped up in my "people you may know" before until now.

I gave birth to our child and less than 3 weeks we got into another fight and I left and moved 2 hours away. For the people who do not know after having a baby they send these documents (birth certificate and social in the mail 2-4 weeks later) but I was in another state and couldn't get them nor do I drive. I called him and asked him for these documents and he hung up on me constantly, blocked me on Facebook too. I don't bother him at all and told him we both moved on and I'm ok with that and I'm contacting him because it's important. Since he's not on child support as a single mom I need help from social services (welfare) and without her documents it's difficult for them to help me.

And by the way he's made no efforts to see our baby or help me financially because he doesn't care so please don't start with the bullshit "you don't let him see his kid "

I only contacted him in regards of important paperwork for our child that I have full custody of. I let him live his life and do not bother him until today I needed something. It's only important reasons or an emergency why I contact him. I never contact him about our past relationship or anything irrelevant yet he hangs up on me and blocked me on Facebook messenger.
For what it's worth I did leave his house and move in Feb and took our infant child because he's a abusive psycho but he's a deadbeat and doesn't want to see/take care of our baby anyway so if he's angry about that he should only blame himself.

My child's father abused me that's why I left him and moved to another state. He also doesn't help me with our baby and said if I put him on child support I'd be a gold digger. He's made zero efforts to be a dad. Since I moved from his house and don't need him for shit anymore maybe that pissed him off? I asked him for our child's social security and birth certificate and he blocked me on Facebook messenger and hung up on me. Both are still at his home and I need both as the mother. Why is he doing this and I did nothing wrong to him but leave for me and my child safety/happiness?
