The dream is telling you what you really want from this guy. You want him to have feelings for you (what he says on leaving) and you want to keep him a part of your life no matter where he is (thus the arm).

The mints may represent something special of yourself that you share with those you are in relationship with. I'm not necessarily suggesting anything sexual, just a special part of yourself that you only share with those you care deeply about. The other two men could represent relationships you have had in the past or will have in the future.

As for resolving this in reality, it will take time before you are able to let go and move on, but you will be able to someday. If you're comfortable discussing your feelings for him in hope of trying to find out where the relationship is going, you could write him a letter or talk to him via webcam.
