I'm in a mono-relation at the moment. I talked with a friend of mine, who is also polyamoric and bisexual (don't know the english word for it), and I came to the conclusion that I cannot stand a mono-relation for a long time. I want to tell him, but I just don't know how. I'm afraid he might end it right away, or that he puts me in front of the question myself. Does anybody have some advice about how to tell him most subtile?
