This is a mainly female forum so it going to be biased, there are plenty of cases where it is the man being used and the man being made homeless and loosing his family.
The law is even handed as far as it can be a married woman has a right to half the married property including a share of any pensions accumulated. Maintaining lifestyle cuts both way there will be changes, family members even friends will take sides, maybe you move to a different area. The house may need to be sold, life in a flat or a rented property will be different, the change for a man is exactly the same.
Maybe your man is earning more, maybe you haven’t been working, that is your choice, if you leave, you have to support yourself. You won’t be homeless in reality, if you have money you rent or buy, if you don’t it’s social housing and benefits.
If you are unhappy and can’t resolve your differences get divorced and start afresh, happiness is priceless.
