Should I tell the father of my baby when I give birth?

So here's the story. The father unexpectedly is very irresponsible. 1st time I told him I'm pregnant the first question he asked was "if the baby was his?" (He's the 2nd and so far last guy I had sex with, he's just an asshole) 2ndly when he finally believes it's his (after we counted the days we're together to my fertile days till I found out I'm pregnant) his next words are "it's your fault you got pregnant, "I told you we're not ready yet" He blames me and accuses me of using him to get myself pregnant. FYI I'm supposed to fly to Thailand last year and I'm working on my papers. That alone is enough reason to make sure that I won't cause any accidents especially pregnancy since I'm the bread winner of the family, he knows that and he said those words to me. He lives in manila and when I found out I'm pregnant I was in the province with my family. Since I got pregnant I decided to stay here for good until childbirth so my parents can help me out. Nothing beats the comfort of your own home. Di Muna ko bumalik sa manila since I also found out that I have sensitive pregnancy. Pag umuwi ako sa kanya not only ako lang nag wowork samen dalawa I'll be burden with household chores which pinagbawal ng ob I should be on bed rest. So I started working from home sa province. Work sleep and eat ang naging daily routine ko. He on the other hand never visited me hence he never met my parents. He also didn't ask about "how my pregnancy is" pag magkausap kame He also only talks about himself tuwing magkausap kame sa phone. When I tried to seek comfort he'll invalidate my feelings and guilt trip me pag di ko siya napadalan pag may gusto siya bilin And he never offered financial support either for my pregnancy.(I understand this part kase wala siyang work) so I helped him find a job only to tell me he'll use his salary to get his car fixed and then he resigned after 6-8weeks? I had enough, I was 6 mos pregnant that time and I broke up with him. I told him, we'll break up but I'll let him see the baby, visit the baby anytime, like relationship lang namen ang mawawala but my family and I will treat him nicely since I still want us to be friends for the sake of the child. However because of how he treated me I can no longer see him as my lifelong partner. I also asked if it's okay if I use his last name for our baby since di kame kasal and I want him there pag nanganak ako And he said. No. If I'm dead set in breaking up with him. He'll disappear from our life. He will not meet the baby and I should put the baby's last name with mine. That I should just tell the baby, "daddy loves you but he is dead" and said that after that conversation he'll delete all the ways we have to communicate with each other. He also said that he was disappointed in me and I made him sad. He never really thinks about me and his child. Now my mom and aunts are asking me to get in contact with him and tell him pag nanganak na ko. Baka daw mag bago ang isip. I can't blame them. A certain neighbor posted on Facebook, basically nilalait ako for being a single mom. Nasaktan sila for me I know. But ever since Nakipag hiwalay ako he never tried to contact me again as in never. And since day 1 ng pregnancy none sa family niya ever asked about me or tried to contact me as well. Part of me wants to let him know and send him at least 1 message pag nanganak na ko this end of the month. Still hoping na may kalakihan tatay anak ko(baka mag bago isip). But a big part of me knows that he'll act cocky and make me feel miserable when I contacted him. He'll probably question me why I'm even telling him that My aunt said I should tell his parents about it instead, maybe his parents would want to see their 1st grandchild from him. But as I mentioned, his parents never get in touch with me at all since day 1 of my pregnancy. What do you guys think?
