If your spouse:
Doesn't work, but also does minimal childcare as all DC at school.
Does very little housework, and in fact has the MIL round once a week to clean.
Can't be trusted with any access to money or cards due to a history of running up horrendous debts or buying bottles of wine everyday.
Because of the debts you have to work overtime every day and wfh several evenings a week.
Rarely cooks for the family.
Has lost their driving license so you have to take the DC to their evening activities.
Frequently ends up hospitalised due to self inflicted injuries.
Goes days without a shower and has days when they don't get out of bed at all.
Has put on nearly five stone since you met and no longer makes any effort with their appearance.
Makes huge purchases like a new car and a dog without consulting you.
With all of that going on, would you LTB?
