Poor you Nannimo, how unfortunate that you stumbled upon something so critical of you, probably written in the heat of a particular moment & not a reflection of your daughter’s true feelings about you.
I was thinking that children sometimes grow up experiencing the fun side of their fathers, but the more serious, anxious side of their mothers. Although as adults we can rationalise this, still the feeling lingers, and although we may rely (too heavily?) on our mothers, the relationship can be strained.
I agree with others - don’t refer to what you read, but give your daughter notice to leave your job, and hold back on the household help you’re giving her. Try to stay friends.
