They’re the exes that just won’t stop fighting. Though Jon Gosselin and Kate Gosselin were married for 10 years and birthed eight children together — a set of twins and a set of sextuplets — the former husband and wife haven’t been on good terms in years. In fact, it appears most of the Jon & Kate Plus 8 stars’ bickering has occurred in the media as Jon has maintained countless times that his relationship with Kate is “nonexistent.”

“I don’t have a relationship with Kate. There is no relationship. Text and email. That’s it,” Jon has revealed. “The nanny comes out and I exchange the kids at her gate or at the bus stop. I don’t physically see [Kate].”

For those of us who’ve grown used to hearing these exes bash each other in the media, you might not even remember what caused their bitter breakup. What led the Gosselins to where there are now? From marrying in 1998 to divorcing 10 years later to now relentlessly tearing each other down in the press, we compiled a complete timeline of Jon and Kate’s tumultuous relationship. Check out the gallery to find out more about the reality stars’ relationship ups and downs!
