Baby daddy advice.

Do I reach out to my child’s father? For context, we never exclusively dated and only slept together one time when I got pregnant. I asked him from the beginning if he wanted to be involved and after seeming quite conflicted,as his dad was never in his life either and he didn’t want to be a deadbeat, he decided he wanted no involvement. (Shock). I spoke to him a couple times during my pregnancy and each time the interactions were very hostile on both sides. At the very beginning my midwife had to phone the police as he was calling me constantly trying to force me to get an abortion. Regardless of me saying I would never force him to be involved, he still didn’t want me to have my baby as he again didn’t want to be viewed as a deadbeat. The last time we spoke I was about 5 months pregnant. I had my baby 2 months ago and informed him 5 days after my son was born. My sister spoke to him to avoid conflict and he said again that he didn’t want to be involved. I was thinking of sending him a couple pictures of my son to see as he hasn’t seen him yet and doesn’t even know his name. I’ve moved out the area and changed my number so he has no way of ever contacting me if he ever changed his mind. I don’t care for his involvement to be honest as I’ve managed perfectly fine without him and never wanted a romantic relationship with him. Either we would co-parent or nothing. I just feel awful for my son as I couldn’t imagine not having my dad in my life. He’ll never know any different but it still plays on my mind. I want to be able to tell him one day that I did all I could for him to have his father in his life. Do I reach out for the LAST time or leave it?
