I'm with you on how hard it is to not contact h. But learning to NOT call my h has lead to more contact...by him!
so take heed of my situation and do likewise. Back way off, no pressure. He's thinking of you all the time! He'll notice the new you when he gets back.
Remember this time is training time. Get the no contact under your belt while he's gone. then you can get that down and move on to the next goal.
