I understand what you are saying...but saying (i was just responding to her the way she responded to me?) while yes, probably truthful is a tit-for-tat statement and well, just sounds childish (and I don't mean that as an insult to you)...you won't get where you want to be by behaving this way.
Saying...I'm not going to continue to give affection to someone who won't receive it. Is also truthful, yet a stronger more confident statement. If she responds in the manner you think she will then...isn't the real problem you are having that SHE WON'T ACCEPT THE AFFECTION YOU TRY TO GIVE? So, if she says the statement of ("i am showing you affection, i am kissing you, touching you, etc -- ") she is deflecting the focus off of the real issue.....the fact that she won't allow you to show her affection in your own way.....direct her back to that.
I remember at one point with my H he used to tell me, "I do kiss you." My reponse eventually became...."you kiss me no differently than my Dad or a friend would when greeting me. I can get affection like that from any of my friends or family. There is an absolute difference."
Also, be prepared to repeat yourself many times before what you say gets through to her. Your tone and actions have to backup your words.
