Kelly,
To reflect back what you said here: you have a hard problem moving on and letting go, like attention, have codependent tendencies. and despite that you felt betrayed by him your ex means very much to you

You consider the problem you are having is that you are leading on your ex by communicating with him via text or Facebook?

It seems to me that the current situation meets both of your needs. You both are staying connected and giving each other attention that suits you two. He may want more but you are getting what you need. Do you agree?

So for the present moment (and that’s all we have in our lives), it works. To get into our heads and worry creates suffering (which I believe that is what Buddhism teaches – correct me if I am in error on my interpretation). Regardless, I believe it is true.
