SIL was renting a 2 bed flat with partner and 2 DS, could no longer afford it and therefore decided later this month they would move into her BILs house.
2 weeks ago found out when DS are alone at BILs house, BIL bullies them, takes food and toys from them if his children wants them, tells his children not to play with them, that they're "germy" swears and shouts at them, calls them every name under the sun etc.
SIL says she has no choice but to continue to move in, SILs mom (MIL) is ranting and raving about how it knocks her sick and she wants to go down there and give them a piece of her mind but "they HAVE to live there, they have no choice" all whilst MIL is living it up, alone, in a 4 bed house.
So MIL has 3 spare bedrooms and a huge house all to herself but refuses to let them stay there with her, whilst claiming the thought of SIL and children living with SILs BIL knocks her sick.
No one else is questioning this but it doesn't sit right with me. AIBU to feel MIL being so passionately angry about the situation but doing nothing to help is extremely weird and selfish?
I wish I could help myself but I have a 2 bed house and a DC myself, so don't have space for an extra 4 people!
