Jenny, I just saw this post and had already responded to you on my thread, so disregard that one.
See, I think he's spewing a bit of crap there. He obviously is NOT okay with you moving on or he wouldn't have run out in the rain at that hotel, earlier this summer. He DOES have it in him, he just chooses not to tap into those emotions for some reason. Depression, maybe. Maybe it is low T...from what I read it can make a man listless and indecisive. Maybe it is, as you said, a deep fear of intimacy. Maybe it is a feeling that he is "no good" at those types of feelings or interactions. Maybe it is that he is plain ol' Mr. Wilson who believes that those interactions are for wussies.
I don't know, Jenny. All I know is that you are a beautiful woman who does not deserve numbness--you deserve open arms and a hard appendage.
