Am I selfish?

I’m 22 and have been dating my bf 34 for about 8 mo. We unexpectedly got pregnant and he’s been begging for an abortion every day, every hour and has threatened our relationship if I don’t get one. I went to my first ultra sound yesterday and heard my baby’s heart beat for the first time. I instantly fell in love. My bf didn’t go with me and says he will not go to any of them because he doesn’t support this choice. It amazes me he’s a fire fighter/ paramedic and saves lives for a living and can’t seem to save his own child’s life. I cry every night begging him to see what I see. All he says is we’re financially not ready, he’s worked so hard to where he is and it’s going to be taken away from me because “ I’m selfish”. He keeps saying I have nothing to loose because I haven’t gone to college yet and only 22. It breaks me because our relationship was utterly amazing. We were best friends and never ever had a single fight and now this he tries to fight with me everyday. He finally gave me one last chance to get an abortion last night. He said I will never ever see the person I fell In Love with if you go through this pregnancy and will hate you forever for choosing my life. I told him I’m keeping our baby. He told me I’m a complete and utter selfish idiot living I. Fantasy land. He broke up with me and said we will never be a thing since you won’t do anything for me. He said that’s what couples do, they take bullets for each-other and you can’t seem to do that. I love my baby. But is selfish the word for me choosing to continue on with this pregnancy? I continue to pray for this man. It’s just very very difficult and I’m in a position where I lost my best friend for our baby. It angers me he gave me that ultimatum.
