Yes have discussed marriage i asked if we could get married ( we've been together over a decade and not even engaged ! ) but he said that's something he needs to ask me but I don't see that happening
This is a ridiculous argument on his part, OP.
You're in a very vulnerable position as a SAHM without the protection of marriage. This isn't even in case you split up, but in case of an accident or an emergency. Unless you are independently wealthy/self-sufficient, it's a very insecure position.
If he doesn't want to get married, he needs to ensure your protection in other ways. He needs to make a will (ideally with the advice of a solicitor to help with tax implications), pay into an independent pension for you, and/or split his take-home earnings in half, with each of you contributing half to the bills and saving/spending the rest as you see fit.
This isn't just for you but for your child as well. Life can go pear-shaped at any moment, even with the best intentions, and it is necessary to make sure, as best you can, that the people you love won't be totally fucked when that happens.
