In my case ILYBNILWY really meant "I'm afraid that YOU don't really love me in a romantic way because you don't pursue me and lust after me the way you used to so I'm not going to love you either."
It's very interesting that you should say this. I would have never thought of that. In our case, I feel that she has told me this because of hurtful things that I had spoken to her. I felt that she was spending too much time with OM in my absence and when she would not accommodate my request that she show her loyalty, I verbally assaulted her for it.
However, now that she has "turned the corner" and decided that she really isn't interested romantically in me anymore, she has taken to wearing clothing that will really grab a guy's attention. Things like spandex pants, low cut sweaters, very tall heels, etc. It all speaks of looking for someone to lust after her.
