BF split up with me on sat, I'm completely devastated as he was my best friend before we got together, even if he was controlling then, and it just feels like I've lost a lot. In most circumstances I'd never see him again but half of his employees are my friends that I met through his place of work and where he works is somewhere that inevitably I will end up going to before the next week is out. What can I send as a message to just say we need to be amicable/polite to each other? Need help please!
