I would change the "happy to speak to you" part. I would put it more like, "If in the future you find you have a change of heart, you may contact me and I will see how I feel about things at that time. I've always seen myself as committed, yet there are hurts that go to the very core of a person. I know God will be with me and I will miss you, but I will be fine...." something like that rather than you being "happy" to speak to him.
