Is this wrong

My BIL saw his ex-fiancé a couple of days ago, been broken up 2 months now and he moved back at his parents house. She told him he’s changed and looked nice. To which my FIL commented, well when they were living together, she barely cooked so now he’s back home, he’s eating well. And he’d complain time to time when they were together “nothing decent to eat“ and go to his mommy for a plate of food.

I don’t get the stupidity that 2 working adults living together and the man still expects to be catered to. WTF is this.
