How the heck do single parents do this!

I have major respect ✊ for every single mum out there. Shit ain’t easy! Parenthood in general is hard as hell, I can’t even imagine how I will cope doing it on my own without my husband. Before pregnancy I used to have so much money that I spent carelessly on designer items without even blinking but now I’m obviously not working (maternity leave), I can’t even afford to buy the cheapest whatever anymore. I actually now rely on my husband financially. Like how would I cope if I am a single parent!
