The Good American founder explained her reasons behind her initial refusal toget engaged on this week’s Kardashians.

“I said, ‘I need to make sure this is a totally different relationship becauseI wanna be proud to say I’m engaged to anyone,'” she recalled. “And that’s whyI said, ‘I’m not comfortable accepting this right now because I’m not excitedto tell my family,’ and as hurtful as that probably was for him to hear, itwas the truth. I’m not ever gonna accept something or give someone false hope,and I said that to him.”

“Going through what I went through was Tristan was incredibly hard,” she lateracknowledged in a confessional. “The hardest part about it all is trainingyourself to un-love someone. This was my life for six years. And we weren’tjust a couple, we genuinely were best friends. He was my workout buddy, we didall these things together. And so learning how to undo all those things, thattakes time. Just because someone does you dirty doesn’t mean you fall out oflove with them instantly.”
