This isn't so much of an AIBU but more of a what would you do in my situation?
for quick context MIL and DPs cousin aren't keen on DPs other cousins GF. DP has two cousins, male and female, the female does not like her brothers girlfriend, and MIL doesn't either.
there has been an exchange of comments made- some nasty. the GF doesn't like my MIL or her SIL (DPs cousin) and vice versa.
MIL recently has approached me with gossip about the GF, and often talks negatively about her- expecting me to join in, i try not to, commenting that she's "only 17, and just a kid, she doesn't know what she's talking about" but MIL doesn't settle for this.
i get along with the gf, but i also get along with MIL and DP cousin (who doesn't like the GF) but seem to be stuck in the middle. i don't want to get involved as i understand both sides.
it's been awkward whenever MIL talks about the GF and i don't know how i should respond to it as i'm relatively close to the GF, and whilst MIL is looking for my support, i'm struggling to give it. for context GF made a negative comment about DPs cousin (her SIL) and my MIL, but i'm one of the only people who understand why this comment was made, and to an extent understand why she made it. not that i necessarily agree, i think they're all wrong, but i don't want to add fuel to the flame by mentioning what i know as it would cause uproar.
AIBU for not getting involved?
WWYD in my situation? i know this is quite vague, but how would you respond?
