UK how to decide which county to move to?

I am a young mum of 22 I have 3 children under 5 and currently living in Bedfordshire. I have been feeling for a while that I don’t want to stay here but feel like I’d be betraying my family if I did so, plus the biggest question is where do I go? I have no idea where I want to be, I haven’t really ventured much outside apart from a little up north in Leeds but I also don’t see myself as a city girl the lifestyle is far too busy.

I want somewhere that provides good benefits (childcare because I will have no family to help out, family days out for a small amount etc.) just somewhere there is actually something to do with the children where it’s not a car journey away (or a long one) and doesn’t cost the earth.

I also don’t want to move somewhere unsafe. Of course when in your hometown you know exactly what to stay away from but I’m worried I’ll move to the wrong area and be stuck there😩 I will also need somewhere that I know will be hiring even if it just a supermarket and close to warehouses for my partner too.

Does anyone have any advice for moving away from home with basically nothing? And does anyone have any recommendations to somewhere there’s lots to do for young families?
