I think this is worrying It's my pride & embarrassment that stops me asking for help, not that I ask him for it & he rejects me
You chose to have a child with this man, you have been together years and yet you cannot even have a conversation about finances.
When Dh and I moved in together, before marriage, despite both being graduates he earned a bit more than me so we put everything in one pot, left ourselves with the same amount of money each for spends, out of that one pot came bills plus money into a savings account.
Since then and marriage Dh has gone on to increase his salary, I reduced mine after having Ds1 but we had a full conversation about money etc and how we would fund my maternity leave and how it would work with my part time hours afterwards before we had a child together. Since then I became a long term SAHM when Ds1 was a toddler as I am partially disabled and we went on to have Ds2.
I did feel like a burden to him but he never made me feel that way, I went from having earned my own money from 14 years old to zero. I found it hard. I have access to the joint account, I am the additional card holder on his credit card as it earns us points and I am free to spend whatever I want.
I have savings in my sole name as does he but mine has more in it. We have been married 21 years. Every year we have a financial meeting and discuss what we have spent over the last year and on what, what our plans are for the next year for spending. In previous years this has included the renovation of our house so new boiler, radiators, double glazing, new bathroom, kitchen extension etc.
You need to be able to talk about money. If he is as good a man and partner as you say he is he should be mortified that you have far less money than him every month, but also, why hasn't this occurred to him?
I have been on MN for 15 years, I wish I had a pound for every thread I have read where women get royally shafted by a partner or husband after they separate, hence why people are saying marriage is important when you are working part time, reducing your own pension contribution whilst he is paying into his and you have no claim on it. I know you say you have family to move in with should things go pear, but family circumstances can change too and you might not have somewhere to go.
