Now they became, in the eyes of those who mattered, a couple-to-be, sanctioned along the way and watched over carefully to make sure they proceeded as directed. In case you haven’t noticed, things are radically different now.
Tell him up front who you are and what your concept of a great relationship is and that you are honestly hoping that will happen someday with the right person but you know those little miracles are not usually created by intent.
Let him know that you are serious about your quest but have no intent of asking anyone along who doesn’t feel the same way.
