(man to girl)
My dear,
Yesterday night I could not sleep and I tought a lot about our discussion.
Thank you for your honesty and your frankness.
Maybe you are right. There are too many obstacles to our love story.
I live very far away from you, can not be always with and near you.
I already have children and I am not yet divorced even if my wife and I are not together from more than 2 years.
I understand you deserve to be loved by someone who will take care of you and will offer you a good life.
I also understand you believe I can not offer you a serious and stable relationship.
I know it is a very complicated situation but nothing is impossible or fixed for ever.
Time will tell and we will have the opportunity to think and talk about it again and later. Maybe you will change your mind and give our story a chance to go forward.
I need to tell you that my love for you is still very strong and that you will always be in my mind and in my heart.
I will not question your decision and I accept it with no anger or hate.
You are a wonderful girl and I was very lucky to meet you, to know you and to love you.
Thank you for all the happiness you brought me.
(It is a bit long sorry for that)
