Dear [recipient's name]:
As you know, Don and I became engaged this spring and had many high hopes and dreams for our future together. As things unfolded, though, we mutually decided not to go forward with our relationship. With much sadness I wanted to let you know that we are no longer engaged. We both have inner peace about this decision.
I would very much appreciate your support and encouragement during this difficult time. Thank you for always being there for me.
