Why do you seek a legalistic answer to such a question? Your conscience should give you the answer. Are you deceiving the other person into thinking that you "might be" a potential marriage partner when you know you are not? Do you both understand that neither or you want to marry the other? If your conscience is clear, if you are not engaged in deceit, why do you seek "confirmation" how to behave? If you are living by faith in that which you know to be true, you do not need the confirmation or approval of any authority other than that inner awareness revealed by your inner voice [which is not to be confused with all the conflicting chatter of words within your head]. After all, if it's not your inner voice that guides you, how could you possibly know if the advice others are giving is correct..., unless, of course, you weigh that advice against that same inner voice? By asking this question, you reveal that you are full of doubt and confusion, evidence that faith is missing. You cannot give yourself faith, but you can be aware that it's missing, which is the first step toward praying that silent wordless prayer, Father, help my unbelief. Remember too, doubt of that which you know is true is what got Adam and Eve in trouble in the first place.
