My bf is begging me to get abortion but I don’t want to

I recently found out I was pregnant from an unplanned pregnancy. My partner and I have talked and he has made it clear he does not want to keep the child and in suggestion would prefer for me to get an abortion. I knew he never wanted a child however he claimed he did see a future with me and wanted a family with me. We talked about baby names however we both understood if we become pregnant anytime soon we will terminate the baby. All of a sudden my mind has changed and my mind and heart is telling me to keep the child as I would not like to go through the process of abortion. My partner has mentioned he will leave me and not be present for me however will be present for the child (he’s not ready for to be a father). I have a strong support system in work and family. When I first found out I was pregnant there were feelings of uncertainty and excitement. I am not worried about bringing up this child because I feel secure financially, employment, and family. My partner told me at first he would support me in what I decide and then following days begged me to get an abortion at first I assumed he would be supportive of me. We began arguing about it and he said that I've always known he didn't want a child and he expected that I would want to terminate it since we have talked about it. (He says I’m forcing him into fatherhood). I understand he does not want a child but I expected for him to nurture me and care for me. I told him to please stop bringing up abortion as I made me decision and cannot force abortion down my throat his response was you cannot force a child down my throat. Apart of wants to keep this pregnancy however I apart of me also wants to terminate it. I already struggle with ptsd and go to therapy, I don’t want to go through the whole process of doing joint custody or stress of fighting for full custody. I want a secure and safe partner to have a child yes I have family and friends to support me. Any words of encouragement or advice would be helpful!
