Kardashian and Thompson had been in an on/off relationship since 2016 and welcomed daughter True in 2018. At the time Tristan fathered a child with another woman, they were on again and had moved into a new home Kardashian had built for their family.
After the episode featuring the discovery of Thompson's betrayal aired, Kardashian tweeted: "We all deserve forgiveness and most of all... LOVE ... Life is full of lessons, teachable moments. We should handle them with grace/love. Even if we are hurt by them."
The star added: "Take ur moment, cry/scream but remain composed remember that Love heals teaches more than anger ever will."
Referring to the onscreen drama directly, Kardashian wrote: "This was definitely a tough episode but there's so much beauty in watching how close my family is. W'll always stick together and love one another deeply (sic)."
