Rules For Dealing With Your Partner’s Siblings
The sibling can’t vent to you about your partner
Sometimes, the sibling may try to complain to you about your partner. That makes sense because you both know your partner very well. But, you’ll have to politely say, “I think you should take this up with your brother—I don’t feel comfortable talking behind his back like this.” You’ll come out looking like a good partner. The sibling will understand.
