Khloe Kardashian and Tristan Thompson will be linked together for a lifetime thanks to their two children.

However, there’s another reason Khloe continues to remain very close with her cheating ex-boyfriend.

You see, she made a promise to his mother, Andrea Thompson, after she unexpectedly passed away last month.

She promised to continue to look after Thompson’s younger brother, Amari, who suffers from epilepsy.

In her Instagram tribute to Andrea, Koko wrote, “Just know, I promise you, Amari will be perfectly ok.”

Khloe has been by Tristan and his family’s side since the tragic loss of Andrea.

“Khloé loves Tristan’s brother Amari and she has every intention of being there to help care for him every step of the way,” a source revealed.

Khloe has no intention of getting back with Tristan in any romantic capacity.

Despite his several cheating scandals and never-ending infidelity, Khloe grew close to his loved ones. This is something she will keep with her forever.
