More of a what would you do than an AIBU. Some details changed slightly. This is long, sorry.
Been with my husband for about 8 years, married for a good chunk of that and we have a toddler together.
I bought the house 15 years ago on my own when I used to earn a decent salary.
I now work a just above minimum wage job and earn less than £18k. I work part time due to childcare and health issues (which I’m not eligible for any support for).
I want to separate.
Neither of us could afford to take on the current mortgage payments on our own, so we’d have to sell. We’d be left with maybe £70k each, but I wouldn’t be able to get a mortgage on a new place on my own due to low salary.
I will have too much in savings from the house sale to be eligible for any sort of universal credit. Rents round here on a two bed would be higher than our current mortgage.
In a few years of renting all of my money will be gone and I’ll have no deposit for buying somewhere else, so nothing to show for 15 years of paying a mortgage. Plus no money to help my child in the future (with e.g. buying a car, university etc).
What would you do? Stay and be unhappy or leave and have no money?
