Thank you, Wife2Kids. I believe you are right, he back to denial.
Well, he is home now. He just stopped by my studio where I work. I was afraid at first that he would beg me to come home, but instead he was actually kind of pleasant. He did say, "I can't believe you're just done with me," but I assured him that I am not "done" with him. He told me he appreciates all that I've done for him. Then we both said "I love you", gave a big hug and a kiss and then he said he was going to go see the dogs. That was it! It was like he accepted the fact that I wasn't coming home. It was almost too easy, though. When I actually go to my Dad's later, that's when I'll probably get the angry/begging phone call.
