First off, I take issue with the idea that going to the grocery is easy enough. In this day of distancing, masks, and can barely get through the store due to all the immense racks being used to fill online shopping orders, it is a real ordeal just to go.
Then sounds like the boyfriend is happy enough to let her do the shopping, bring everything in, AND put everything away.
He should take a few turns at it, and see if he has any different attitudes. JMHO
I agree. Maybe she’s trying to tell him, “Hey, I do the shopping and lug it in and out of the car, YOU can put them away!”
Of course, she should just come right out and say that, instead, but maybe she HAS said it dozens of times, and she’s tired of it. He can put the stuff away.
