Your W sounds like mine to a large extent. My W is very sensitive and my bad moods would affect her greatly. I definitely relied on her for my happiness especially when depressed and that put way more pressure on her than she was able to handle.
Are you initiating good night texts or just responding? That wasnt clear to me. If your W is anything like mine she needs to feel completely free from all the pressure we put on them, the expectations, the burden of making someone else happy. Initiating contact puts the pressure back on, it raises their spidey-sense that there is neediness or pressure. I know that it is a common refrain here that you cant "nice" your way back into your WS heart. For me that is tough as well, because I want to be friendly and pleasant in interactions as well.
I am sorry I dont have answers for you Did, but I am following your thread and wanted to offer some support.
