"Parents"

Anyone else have "parents" who talk shit about them to siblings because They think they don't talk to each other? Apparently my dad was telling my sister all about how horrible my husband and I are doing. How we're in financial ruin and never talk to them. I'm the only one who ever tries to talk to them and they never even ask about my daughter. They've said they're proud of us, but then they say shit like That? What would you Do? would you confront them and then ignore them, or just let it be and stop attempting to contact them? Like it broke my heart and I'm so fucking angry but I don't think going off on them would do anything besides making trouble for my sister.
