- Dear god. It's not judgement it's knowledge of how utterly and completely that changes everything. Every 18 year old I know is going off to uni for the first time. Their first time away from home with only basic domestic skills (baking cupcakes, possibly some form of pasta. Pot noodles). Hanging out in 'Spoons. Discovering politics and utterly convinced they they are wise and grown up beyond their years.
You are heavily pregnant with a total arsehole of a bf who says things like 'why would I choose you over my family' and wants you to become his personal domestic slave a SAHM.
Ok so your parents. Do they 'say nasty things about him' because they are nasty unreasonable people who don't love you? Or do they say them because you are 18 and they can see very clearly that he's knocked you up and is now treating you like shit? Because he damn well is.
Are they completely wrong and stupid? Or do they have more experience of little shits like him and know exactly what he is? Are you doing the 18 year old thing of proving a point? Because being an actual adult is about understanding 100% when you have made a mistake or got it wrong and dealing with it.
You crawling back to an abusive bf and his even more abusive father would be the biggest mistake of all.
Getting support from your family and working as soon as you can after having your baby to build an actual career would be a grown up decision. I don't know your family but be careful you are not still stuck in a teenage dynamic with them where you automatically oppose what they say and go against them just to break away.
But then you ARE a teenager and you ARE supposed to be at the point if breaking away which is why those shitty years of you arguing with them all the time exist. The problem is that you have nowhere safe to go and other 18 year olds might be flying the nest but they are not self supporting. Mummy and daddy are still bankrolling most of it and they don't have babies to look after.
So your best bet would be to repair your relationship with them, move nearby hopefully with some kind of housing benefit, and start working hopefully with them providing some free childcare - but you can't expect that full time. Maybe study part time. Maybe if you can find a shared house with another young mum?
Just staying on benefits as a single mum won't be a life lived well. Staying with this prick of a man will be much worse. So you have to choose sonething else.
