This is too personal and there are to many variables for a clear answer to be possible.
Personally, I would never be a single parent voluntarily. It is easier than with a bad partner, but still much harder than with a partner. All the decisions, sick days, bad days, school meetings, budgeting, cleaning, etc will all fall on your shoulders. I still remember a week that I was really poorly and I was in an added panic because with no family around I just didn’t know what to do with my DD.
Another thing that most of us don’t really talk about is that babies and young children are the easy mode phase. It gets increasingly more difficult, costly and emotionally taxing as they grow. It’s not just wanting a baby, it’s wanting a whole person to raise to adulthood.
If you really want to do it, I’d try to get as much of a community around me as possible. Join a local church if need be, you’ll need all the help you can get.
But if it was me and I had to do it over, I’d probably look into volunteering with children and/or fostering.
