She took to Instagram on August 24 to write in tribute to her friend, "Never can say goodbye. This is just a page in time. I’m happy that all the best is yet to come for my friend B. Best Mom to Bryn, Biggy, Smallz & entrepreneur as she continues to empower others."
After confirming the news of her exit, Bethenny commemorated her time on RHONY in a lengthy Instagram post, writing in part to her fans and followers, "I am so grateful to you for sticking with me through everything. You started this journey with me in my tiny apartment in my late 30s, wondering what would happen to me. I was broke, single, had no family and no idea what the future held. I had big dreams and I never stopped, but I honestly didn’t know if I would ever get here. You helped me to get here. I would read your letters and messages and grow from your struggles. You would give me your honest opinion about my products and projects and helpful advice about divorce, relationships, motherhood, miscarriages, health, and surviving the death of a loved one and almost my own. You have shared your ideas with me and I have been inspired by and learned from you.”
Bethenny concluded her post by saying, "Thank you so much for your love and support... I love you all and am so lucky to have you in my life!"
