MIL did someone really horrible (lied to someone about me and DD so she would receive something we were going to be given).
It’s the last straw and I have blocked her number because I refuse to let her get away with this without consequences.
FIL rang, I answered (I didn’t recognise his number, he’s never rung me before) and asked why I was being horrible to MIL! I told him what she had done and he said “Proof, or it didn’t happen!”
I’m not going to “prove” anything. It would mean involving the person to whom MIL lied and putting her on the spot.
He doesn’t have to believe me but to try and demand proof or DD and I are liars is twatty, right?
