The silver lining to all the drama she has had to endure is the beautiful daughter she got from him, True.
However, Khloe probably realises the effect this will have on her daughter when she grows up, so she's posted a very telling quote that seems to be directly for Tristan.
"Dear men. Close your eyes. Imagine you have a daughter. Imagine she is dating a guy just like you. Did you smile? No. Then change."
Yikes. She has a GREAT point though.
