I can't believe some of these comments!
Why did you ask him not to bother? Is that not what you truly meant?
People say not to bother all the time, because it sounds grabby to say "I want x/y/z" Her husband is a fully grown man, who bought his own Mum flowers and wine for Mother's Day, so he knows full well, that he should have got something similar for the Op, from their 3 year old.
Honestly though you are not his mother?
What? Where does she say she is his mother? He should have bought something to give her from their daughter. It's not rocket science, is it?
Of course Op is upset. And rightly so. DH went to the shops and purchased ONE bunch of flowers and ONE bottle of wine, for is own Mum, how hard would it have been to pick up TWO of each and acknowledge how hard the Op works all year to care for their child.
Jeepers, I used to get DH a present from the dog for Fathers Day (before she passed).
