Father lied and said I did nothing for Mother’s Day. Still expects me to pay my sister

Yep.

He threw me under the bus for not doing anything (I did a card and chocolate) after saying oh let’s split for flowers.

Then Mother’s Day: throws me under the bus, throws a tantrum, calls me selfish.

Now my sister and him are demanding money (10$ because ya know, breaking the bank here boys!)

I have 0 clue wtf is going on anymore.
