OP - this is the hardest decision I’ve ever had to make personally - and despite being in a loving relationship (and having wayyyy less savings!) I kept the baby because I wanted to, but became a single mum over a year later due to the man.
I want to highlight that as mums that want our children, we make it work. I think it’s when you don’t want the pregnancy or the child that I would think twice - because you don’t want regret.
If you want to be a mum and the idea of the baby fills you with a little bit of excitement (even though it’s scary and there is lots of planning to do), then maybe you have your answer. If you want to look at options and see how they make you feel (don’t bring the dad along, as this decision is about you), then do so.
I’ve seen PP comments about red flags with your ex, and I want to remind you to be strong and not to put up with his BS. Coparenting and shared parenting with a bad man is another battle, but look into your rights and protections - and make sure you set boundaries for yourself. Don’t let him in your life, but you can monitor what he is like as a dad - and let him into the child’s life.
Get your support network together too. It’s an emotional time.
But also deal with the practicalities of where you will live, if you can get your savings down from purchasing a place, think about how much you will have left and how much runway that will give you - as realistically you will be taking 1 year out and maybe another few years rebalancing yourself as baby gets older and you find your work routine.
I do know women that have ended up with jobs during pregnancy - is there anything out there or is there a way you can speak to your existing employer about hours and contracts?
It is scary, but as a single parent, that has a small network of other single parents, we somehow make it work.
