How can I be happy for him and his promotion if it means I will be losing him?

i spend lots of time with my boss. we work together and play together. over the months I believe that we have developed feelings for each other that neither of us will admit for the sake of being professional at work. recently he got a promotion, which means he will have to move to another country. I am devastated at this news, and when he told me he said many wonderful things and held me while I cried. within myself I know that I am genuinely happy for him because he deserves this reward, but i'm having a hard time dealing with this loss and am a total mess. what are the things I can do to focus on the positive side and make this a happy transition for him?

although he's gonna be in another country, now you might be able to look into a relationship because he will no longer be your boss. you can stay in touch and visit also
