['That is a sad thing to hear. I hope you are happy to be rid of them both now', 'Why was it sad?', 'Because my life changed so much. I lost my best friend and my boyfriend at the same time.']
My condolences, I hope you are doing alright now.
Once, my boyfriend left me for my friend. I felt very left out since I no longer had either of them in my life. It was a sad time.
