First of all you weren’t on contraception and having unprotected sex, this means you were trying to conceive.
Secondly, if I was your ex partners parents I would be asking you to consider this (not forcing you into it) as your own parents don’t seem to have woken up to the reality of the situation and ask you to think about it or even ask you to think about the reality of what it will be like being a single mother.
You say you are financially stable, yet stay with your parents. Do you have a deposit saved up to buy your own place? You can’t rely on your job allowing you to wfh while looking after a toddler (most places are savvy of this and are introducing policy prohibiting it) and you can’t expect you will always work there or WFM. Do you know how much childcare costs. Do you make enough to cover mortgage, bills, childcare, food clothes and transport?
My daughter has just turned 2, I am with her Dad and we are supported by our families. But it is relentless, carving time out to do household tasks is hard, never mind looking after yourself and forget about socialising. I cannot imagine how hard it would be to do this as a single parent.
Then you also have the co parenting side of it. He is either going to continue being a loser and not showing up for his kid, so your heart will break each time you have to tell little Jeremy his daddy isn’t coming to see him again. Or he will fight all the way wanting 50/50, he may or may not get it, but you have to face reality that at somepoint you are going to have to pack up the most precious thing in your life away for days at a time where you have absolutely no control in what happens. Good co parenting is possible, but from what you have said it doesn’t sound like you or the dad are mature enough to make it happen.
It isn’t impossible to make it work, but your situation certainly isn’t setting you up for success.
I hope you are being 100% honest with your midwife at the booking in appointment about the conception, your finances and plans for childcare and your current relationship for the babies father. They need this to give you the right support and do the correct safe guarding.
