Andrew, did she say anything about the IC appointment?
You're doing so well, so stay strong. I know how hard it is, and especially when she keeps a lot of her teenage behavior (i.e. FB thing.)
How do you express your anger? I once told my H I was scared of him and he said the same, that he himself was the least violent person on Earth. But I wasn't afraid he would hit me or anything. I was afraid of how he would make me feel with his attitude and his comments. So I started retreating and staying away from him. Just wanted to tell you what I went through so you can maybe empathize a little with your W. Not sure if she's feeling the same. The key is that she feels good about herself in your presence.
