Reading through your thread. What I find to be odd is that he is older, yet is not able to make more of a commitment to you by defining the relationship. He also referred to it is an "affair". I also wonder, since you had stated you wanted to perhaps keep things open for your husband, then also said you would never be back with him again, if "G" worries that you may wish one day to return to your husband and that's why he is so reluctant? I strongly suspect that that may be the real reason and he's not talking about it with you. Why else refer to this as a "little affair"?
