As someone who has always worked and paid my way and never taken handouts from anyone, and who comes from a family who is the same, including all the men; father, grandfather, great grandfather, uncles, brothers etc, I'm afraid this would be a dealbreaker for me.
All the men in my life (including my husband,) have been hard workers, who stayed in the same job for many years, and got their nose to the grindstone, and looked after their families. I simply couldn't tolerate a man who was flaky, unreliable, snappy, angry all the time, blaming everyone but himself for everything that goes wrong in his life, losing job after job, and throwing his family in the financial mire.
He won't even be able to claim jobseekers allowance, or housing benefit, or council tax benefit or ANYthing, not if he has been sacked.
My DH has had his moments when he has had arguments at work and claimed it's not his fault, but he has never been sacked - not in 36-37 years of work. He's not perfect - no-one is - but any man who is constantly being sacked - or even constantly giving up jobs and moving onto another one (several times a year,) is not someone I could be with.
I know several women with men like this, and they are always walking on eggshells, worrying about finances, borrowing money off people to make ends meet, and looking 10 years older than their age because of the stress. Being married to a stroppy, unreliable, immature manchild will do that to a woman.
Obviously if DH couldn't work because of health reasons or if he lost his job through redundancy, that would be different. For a start, he would not have deliberately and irresponsibly put the family's welfare and financial security in peril. And also, he would be able to claim benefits until he got another job (or until he was well again.) There's none of that if you're sacked!
As I said, dealbreaker for me. I'm afraid I would be leaving this man.
Sorry @PoppyDX93 You are worthy of a better man than this. Don't look back in 30 years and regret your life.
