Spotlight Her Son
If there's one thing you and your meddlesome MIL have in common, it's that you both think your partner is quite a catch. So don't let her forget that he chose you and that the two of you are a team. Use "we"—meaning you and your man—whenever possible in conversations with her, and share anecdotes about her son's fabulous fathering abilities or achievements at work. Above all, keep any marital spats on the DL from the MIL!
