You might not find someone else again, that’s true. But it might be better to be alone with the children than to spend your life taking orders by text from the lord of the manor.
And hoping against hope that if you are a good enough washing machine he will love you again. ( He won’t of course. Because no one loves a washing machine - they either function or they don’t and we replace them.)
How many years can you live like this pretending that everything is fine to the children and him. Because no one likes a grump do they ? Put on that happy face ! Swallow your unhappiness and your basic human needs. Try not to get depressed.
How long can you go on providing sex on demand to him but never expecting intimacy or love . Or even having sex when you want it.
Keeping up appearances to friends and family. And being desperately lonely but not having the freedom to seek love elsewhere.
How long until your youngest leaves home? Ten or fifteen years maybe. Can you keep this up until then ? The only consolation I can offer is that you certainly won’t love him by then - you will despise him for his hateful arrogant behaviour, his selfishness and what he is doing to your children as well as you.
I’m so sorry, as a PP said you do deserve a lot better.
