He wants me to get an Abortion

We already have 2 kids and this would be our 3rd. He says he’s not ready for another baby and that I would be doing it alone if I have it. I’m torn because I had HG with my last pregnancy and I couldn’t do anything for months. I wouldn’t want to go through a rough pregnancy alone and this would be my 4th kid because I already have one from a previous relationship. Oh and to top it off I lost my job last month. I don’t know what to do. Any single mothers of 4 or more kids? How did you do it
