Why don't you do what you want to do? Find your own place, rent or buy. Live your life. Not your H's life or the life you wish you had with him.

Listen, I'd rather you rush out than linger if they both feel false, pick the one that says I have a life, tyvm.

Bit contrived that you rushed out and " oh, I was going to ask you to go shopping...."

Kind of like " oh, you have plans? That's too bad, I was going to see if you guys wanted to come over/ do something/ have dinner etc"
