friend issues....

Recently, my bestfriend of 11 yrs told me hes going to ask his girl to marry him. And he knows i have feelings for him but due to us being miles apart we can't be together hes told me I'm important and he loves me and he knows it sucks we cant be together but even though he is with her he still makes sexual remarks and when i confronted him he said i was selfish and childish cuz i was upset about him fetting engaged to her. i ha e sat and listened to him say she doesnt satisfy him and he feels empty and that he wished i was there and then goes and says this... has anyone been through this? i have nobody to talk to about it and it really hurts i can't even talk to him.... If it was you what would you do?
