Don't get into the drama, but do tell them you are not together anymore. Just say something short and sweet, like: "I'm sorry about the problems my previous partner has caused. However, things have not worked out between us, so we have gone our seperate ways. I assure you I will continue with the level of professionalism you had come to know me for." Donuts, or a little extra $$ for your purchases will help. Good luck!
