my sister is going through the exact same thing rn. and babe, i’m so sorry, but some people just never stop. her friend is the most negative person ive ever met. my sister tried to talk to her about it, but her feelings got hurt, and nothing changed. 2 years later she’s still only complaining about work and her husband. i suggest talking to her asap, see how she takes it. and if she doesn’t take it well in any way… im sorry girl
