I think the separation is the best thing for both of you too. I know you are sad and i know it is hard, but in time you may find yourself enjoying being there alone without all the tension. It is OK to enjoy it. It doesn't mean that you don't love him or you don't want your marriage to work out. It is ok to be ok. I had a hard time grasping that concept.
He needs to be independent. Even if he doesn't want to, he needs to be. He doesn't appreciate the things you do becuase he has never had to do them himself. He will find out what it is like to be a grown up.

I am glad you had a laugh. It does feel good doesn't it?? As time goes on you will start to have more and more of those moments.
