7 Things you should never tell people about your relationship

2. When your in-laws piss you off.

It seems like everyone bitches about their mother- or sister-in-law, but Firstein says you should try to bite your tongue if you can. You never know when word is going to get back around to your husband (or if he simply overheard you in the other room), and that can make him resentful, “as typically people are defensive of their family,” she explains.

And again, it’s not helpful. Sure, it’ll make you feel better in the moment to get a frustration off your chest, but ultimately the feedback you get from friends will be personal and likely drawn from their own experience. “That has nothing to do with you and your situation, so it’s safer not to risk it,” says Firstein.

Instead, go get in a workoutto blow off some steam, then come back and talk to your partner, so you can work out a solution after you’ve had some time to cool off and can speak (and think) more clearly.
