But since you don't live in the home anymore, I would make a mental note in your head to NOT do things for her that is out of the realm of the children. She has chosen to leave you, she has to come to terms with the consequences. Big and small. No other reason than for you to start respecting yourself and not regret being 'made to do' things for her, even though she didn't actually 'make' you but is just complaining verbally. OK? Set boundaries, respect yourself. It will make you feel a whole lot better.
