I don't even know what to say to that, iwc. You are stressing about worrying him for a few hours when you have spent the whole day at work (not to mention all the thousands of hours previously spent) consumed by him?
Ok, so send him a text to say that you want some peace and quiet tonight so you are turning your phone off. Then turn your phone off. Let me tell you, it will probably hurt like hell. But that's what we're all here for. Talk, read, listen to those downloads, do your hobby, go to bed, sit in the cupboard under the stairs with a blankie over your head. Whatever. But I know that until I found out the the world didn't implode without being umbilically linked to someone else, then I was totally stuck in my recovery.
Of course, you don't have to do anything anyone suggests. But sometimes it's time to pee or get off the pot. And you have been provided with a great opportunity to let go.
