Have you ever been in love with 2 people at the same time? Over a long period of time? What happened? Did you ever choose one over the other? Or were you the "other" woman/man in both situations?
Perhaps you don't believe someone could love 2 people. Maybe you feel that one of them would be shortchanged.
Whatever, I would like to know your thoughts. Of course, you should not name the parties involved. Use the comment link so others can join the dialogue.
