Pregnant but he wants me to have an abortion

I found out I was pregnant two weeks ago me and the guy have been seeing each other for nearly a year now but we have previous history. His got 2 young children however I told him I’m pregnant last week and just needed sometime he replied with saying “Uno I can’t do this baby thing again” and that was that. Today I told him I’m keeping my baby and that I’m not going through with an abortion I had one years ago and lived with the regret and grieve. I’m now really upset he wants me to have an abortion but he’s blocked me.

Should I just have the abortion I haven’t told any of my family I’m pregnant I know they would be very supportive but I’m scared of the embarrassment of having to say he doesn’t want anything to do with the baby 😢😢😢
