Your DH has a polite manner even though he has had stroke. It’s his way and he isn’t going to change now people who know him won’t take offence.
My dad was old fashioned and used expressions like darling and love. He was a lovely character and I wish every day he was still here but he didn’t get over his stroke.
People who don’t know him and who aren’t woke 24/7 will probably dismiss the darling expression. You really don’t need to stress about it and don’t let it stop you going out.
