I have trusted you with my heart. You have trusted me with something that is very important to you and I understand that. I am telling you that you have nothing to fear, your heart is my heart and I will cherish it.
Most guys just can't come up with statements like your husband made without at least giving it a little thought. Because it is foreign ground to them. They kind of have to take a dry run with it in their heads.
My thoughts are that his statement is from his heart and it was very sincere.
