<human>: I've (25f) been with my bf (27m) for over 6 years now. Last year we moved in together, and it was really wonderful. However, unexpectedly I received the opportunity of a lifetime, and with his encouragement I moved to the other side of the world to follow a lifelong dream. Now it seems to follow this path I definitively will not be living in the same city as him for at least the next foreseeable 8 years unless one of us (most likely him) is willing to change their career path. 
This past year has been a huge challenge and I am overwhelmed just thinking about how to keep this relationship afloat. For  a long while now, I have been thinking that it would just be best to cut our losses and walk away. He is thinking otherwise. He would like us to stay together, and is literally trying everything he can to keep it that way.
I am going home for a month soon and he is spending his time planning a million activities to make it as fun and together as possible while I am there.
If this was not a problem enough, I have recently developed feelings for a man I work closely with. We became good friends this past year and I have since become very attracted to him. Last weekend we went dancing with a group of friends and we wound up staying pretty close the whole night on the dance floor.
I am feeling guilty and confused and overwhelmed. Until last year I thought that my bf was the one I was going to marry, and spend the rest of my life with. My whole life has completely changed, however, and now I just don't know how that would work, or if that's what I want.
I am not stupid, I know that I need to walk away from this emotional affair and be open and honest with the bf when I get home. I just don't know how to convey this to him, or to walk away from my friend without hurting him.

Can you provide a brief overview of the text?
