As relationships become serious I think it is important to be open and honest with each other. BP is an important aspect of your life. It took great courage to share this with him. I think it could be positive that he is observing your behavior rather than assuming everyone will be like his relative who is untreated. As you are stable I think it will enlighten him that a relationship will not be fraught with emotional upheavals that his relative may experience frequently. At least you will know that his decision will be made well thought out and with observed data. I think that his decision to have you come down to San Antonio is a very positive sign. I am so happy you have found someone whom you are so enamored with. I wish you a long relationship.
