SIL has turned up at our house in a state because MIL crossed boundaries yet again (let herself into her house while SIL and BIL were at work). Her family don’t live near and anyway she needs to go to work tomorrow, so she came to us.
She knows I have the same problems with MIL (we’re married to brothers, MIL’s sons) but my DH is understanding and refuses to let MIL have a key. BIL lets his mother do anything she wants for an easy life.
Except it isn’t easy anymore because SIL has walked out.
DH not in from work yet. It’s going to hit the fan when BIL/MIL finds out SIL is here. She’s really in a state, says she’s leaving BIL (no children).
Any advice?
