Posted in aibu as need advice asap.
Last week my sister finally broke up with her bf. He was financially abusive and he cheated multiple times on her and got drunk most days. She ended up behind in her rent due to him. He give her 500 pound towards her rent a few days before she broke up with him.
He wants it back she told him no.
Now he told his bank he transferred it by mistake which is a lie but his bank is now saying they will take legal action if she doesn't pay it back.
Shes a mess just now.
