I am so very sorry and perplexed with the scenario. I am astonished with what women put up with. Well not just women, men too. Yelling at you for showing him listings. The what...Yelling is only acceptable when it’s “get out! house is on fire”. Why are you defeated? He holds extravagant amount of power over you.
If you aren’t independent you can start now. Your kids are grown. You can get a job and he’ll pay spousal support to supplement your income and you’ll have half of whatever he put for a retirement. You’ll be fine. You sure don’t need him. Sorry but no one would be yelling at me. This is not acceptable
