To be honest I just did this to piss him off and to get a good laugh. He wanted to get a rise out of me and I know he wished I had more to say like usual. But just ok ... I enjoyed that.
To be honest, I think it would be even more effective to not respond at all when he tries to hook you in. I think your texting him the ok shows he's still important in your life and you should try not to text unless it's actually related to business or something important. I mean your goal shouldn't be to piss him off, but to get on with your busy life and ignore him as much as possible. Karen
