Agree with your H. If he is wishy washy then agree that you are too and don't be affectionate or ML with him. He needs to feel that you are slipping away to make him not want to lose you.
If he wants to get back together or is thinking about it, I was told be KEEP to give it atleast 1 month of playing hard to get before agreeing that you want to get back together too.
Now, I have not followed the above advice like I should have in the past. I always said "yes" to ML. My LL is physical touch and that is what made me feel connected to H thru all of this. I now realize that I need to let go of all physical touch inorder for me to detatch and move on.
So my advice only comes from my own experience. Do what you feel you should. What will move you closer to your goal??
