Khloe Kardashian's family is not happy she's getting back with Tristan Thompson -- and that's a major understatement -- but they're not going to lobby her to kick his ass to the curb.
TMZ broke the story ... Khloe was spotted with TT at a Cleveland restaurant Friday having lunch with friends and then showed up at the Cavaliers' game Saturday to support her baby daddy.
Our Kardashian sources say Khloe's family is outraged he humiliated and betrayed her right before she gave birth to their daughter.
