Cades... of course you're not being overly sensitive. I think the thing is that every single one of us wants to be back to the place where we feel secure in our M. Whether we are piecing or just learning about an A or struggling in limbo-land, we all yearn for that safe place again and are willing to do whatever it takes to get there.
With that said, maybe all of the contact that you are initiating is enough for him right now. Are your expectations unrealistic? What if you backed off the communication and see what happens and if he initiates contact with you...
