Well said! I don't think you are pushing him at all, Doglover. In fact, you are being an absolute sweetheart by making him dinner, trying to have a conversation with him, etc. (You are better than me, I don't think I could find grace in my heart to make dinner for someone like that!)

And if he really wanted space, he could spend a night at his buddy's. But he comes home every night, and shows off to you that he is ignoring you by sleeping right next to you with his back turned to you (again, passive-aggressive).

But to second what Open Eyes said, please make sure you get some sleep, eat well, and take care of yourself so you can have the strength to approach this challenge.
