Demanding financial stability from partner

[LilBlueberry]

I work full time while Partner is working full time for 4 years now on a business he started 7 years ago. I supported him when he said he wanted to resign from his previous job so he can focus on his business. The past years were not easy with him just being able to pay himself more or less £1.5k per month, sometimes none at all. He's keen to have a child this year but so far we've not been fortunate to bring home a baby. However, I'm extremely worried about his financial position and dead scared that the financial and caring responsibility of raising a child would fall mainly on me - we both don't have families around so that makes it tricky too. He feels like I'm no longer being supportive and not believing him anymore that he could make his business work. (To which I have emotionally/badly responded by asking him what has he been giving me for him to ask so much - which was really reaaly not good! I shouldn't have responded that way ) But AIBU for asking him to sort out his financial stability if he's wanting to have a child?

Where do you live? That salary in the south is going to be a drop in the ocean but some places further north would be okay. Is there scope to make lots of money but he isn't doing it right or is it just not a high earning industry?

Thanks - We're not from the south so what he's earning is enough to support himself and also our shared expenses at home but otherwise might be a stretch with a child and also just thinking about nursery fees. Industry wise, a bit specialised and turnover of projects are quite long and dependent on a lot of other stakeholders before they are able to lock on a contract hence the issues of having certain months being unable to pay themselves.

There is only a certain length of time you can support someone to start a business and it's a form of manipulation to talk about you not trusting him.
Sit down and itemise all the bills. He needs to take up a part time job to pay more of his share. What would he do if you weren't on the scene..starve???
You have given him every opportunity.
There are too many men messing around on some mad business idea while his wife pays the bills.
