So, ex mother-in-law (not that we actually married but long term relationship) has finally got social media. Has sent me a friend request. That is a hard no from me! But aibu? I don't really talk to them anymore, odd text here and there, civil when we speak or meet. Obviously,I am happy for them to be in GD life via her dad, but just do not want them on my social media page. That's not unreasonable right?
