Yolanda Foster wasn't thrilled to hear that Lisa Rinna had been talking about her Lyme disease behind her back, but on last night's Real Housewives of Beverly Hills, the two women sat down in an attempt to mend their relationship.

While Rinna admittedly participated in conversations in regard to Foster's potentially fake illness, she didn't feel good about it, and when she met with Foster, she apologized for entertaining such controversial comments, and Foster appeared to forgive her--at least for now.

"Lisa Rinna's visit…I feel reluctant, because even though it is hard to look back, the truth is that I've let it go," Foster wrote to fans in her Bravo blog on Tuesday. "I don't have an ego in this or the energy to hang on to negativity. The short of it is I felt tremendous disappointment in hearing the women continuously cast doubt on my health journey and especially that of my children. It doesn't feel good. But it's real life, and I will only seek to control what I can."

"The best apology I could hope for is changed behavior, so let's see what the future brings," she added.

During last night's show, Rinna spoke of a conversation she had regarding Munchausen Syndrome, in which sufferers claim to have illnesses they actually don't have. However, Rinna has never actually stated that Foster is faking her illness. Instead, she appears to be completely convinced of her Lyme disease diagnosis.
