Prego with intent until given a big surprise

So.... found out I’m pregnant (after taking plan B) but bf doesn’t want to have a child yet bc of where we are at in life. I went back to school to change careers but i am almost finished as well as he just finished. I would have to take a break from school which i did once before. (Not a fan of doing so but i’d have to given what i went back for) I know neither of our parents would be supportive yet at this point. We also work together (only one person knows about us). We are a new couple as well. He wants an abortion but i am indifferent in the decision. His view is it’s “just a bunch of cells”. Although, I completely respect and agree in the right to choose the termination of a pregnancy, I can’t help to feel indifferent about doing so. I am 36 and he’s 28. We both do not have any kids. He wants to wait at least a year and travel and be a couple first before adding kids to the mix. So we went to have the abortion at the clinic and prior to the procedure, they did the ultrasound. Well... SURPRISE, it’s TWINS!! I had no idea. Welp, I did not go through with it (i needed more time) but he keeps pushing it every second of every day so it feels like but I’m just unsure especially given it’s twins. One, i would have just done it but two, i cant help but feel indifferent. I’m not even 8 weeks yet but I’m putting on the weight fast. People are going to notice very soon and i have been avoiding my parents especially my mom. I’m sooo not ready for instant kids but I can’t help to feel sadden by it. I’m not a spring chicken anymore and kids may ir may not be in my future. It’s hard enough to abort one let alone two. Nobody else knows but him and I and If I decide to abort, i am telling a single soul. Anyone have any thoughts on the matter or any good insight?!! Thanks in advance
