Good point. Congratulations!
Me and my fiance are both divorced, thus, we have been engaged for over three years. Additionally, we still have not set a date. She does have a ring, however, and a rather nice one at that. I am not sure if we will ever actually tie the knot, since we both had two sons when we started dating and have no desire to reproduce further. Being in a non-married relationship has been so much better than our marriages I am not sure either of us wants to change anything. Sort of the "its not broken so don't fix it" philosophy. It is funny to me how much our married friends are bothered by our extended engagement.
