I completely understand what u feel, i myself experience the same thing, i fell in love with a married man, we both know that our relationship will not work out, so for short we both agreed to stay friends, and the time were discussing about it, i feel fine with it, but actually there's no single night that i dont cry, until now im still crying about it, it hurts sooo much.
I guess the reason why it doesnt hurt that time when i was with him is bcoz, I want him 2 see that im strong and i dont want him 2 worry about me and besides i know our situation and he didnt intend 2 hurt me, and i completely understand that what we decided is for the best of everyone. But in reallity my heart is bleeding coz his my life not just a part of me.
As for u, maybe it doest hurt that time coz u knew that he didnt do anything wrong 2 end ur relationship(correct me if im wrong), its just that he just need to move away(maybe bcoz of his family is also moving away or for what so ever reason, since u didnt state why he is moving away), and also u said that u knew that u were about to break things off bcoz of this, so it means u already accepted this 2 ur self, but then the truth is always there, u loved him, his a part of ur heart and soul, no one can deny that.
Well just think that its not the end, his not married(not like mine ), and maybe ur path will crossed again and in the end its u and him after all. It might work for u to feel better. Im thinking of suggesting u about long distance relationship if u still have communication with him, but i know its hard, and maybe it will get things worst, so erase that one, but u can think about it anyway, and always think that there r lots of people who has lots of troubles than u, and ur still lucky about it Hope i helped. Wishing u more happiness.
