Oh wow, this is truly painful. I don't know any other thing that hurts more in a loving relationship than finding out you're not compatible with the other person by factors out of one's control
I'm so sorry you had to experience this. But hey, this way, you both can go through life without becoming a bane to each other's experience. You'll always treasure what you had knowing that you are deserving of something even better. And so is she.
Thank you for sharing this.
