Pregnant and going through a divorce

My husband and I are splitting up.
Among other things, because I want more kids and he thinks one is already too many.
He kept me on a string with things like, "we'll stop the pill when she's 1.5," "when she's 2.5," "after Christmas," "when she starts primary school," "financially I'm scared..."
In the end, I stopped the pill several times, but then he told me to start again.
It led to a lot of arguments and stress.

So now we've decided to divorce and he's moving somewhere else.
Despite everything, there's still something between us (so also in bed).

Last month I had a pretty bad stomach flu, but didn't think much of it.
This morning I held a positive test (which I already suspected due to being incredibly nauseous, sore breasts, feeling cold, everything smells bad around me, I have a super sharp sense of smell, headaches, and frequent urination. 1 plus 1 added up for me...)

My (ex-)husband wants me to have an abortion. His future is ruined due to alimony, he doesn't know if he can still buy that house, his freedom, and whatever else.
But abortion is really not an option for me! After years of a huge desire for children.

It might not happen the way I wanted (I'm a stay-at-home mom and will end up on welfare, the child will grow up with divorced parents and the father doesn't really want it).

But I'm staying positive!
Since he's hardly ever home anyway and I'm already raising our daughter mostly on my own, I expect I'll manage this too.
I'll just keep applying for jobs and see where things lead!
