I'm sorry you are having such a bad day, gf. Has your H given you any indication he is willing to put in some work of his own?
I noticed that your letter was patterned after the Love Letter in "Men are from Mars, Women are from Venus". If your H has indicated he's willing to put some work in, then maybe he could read that, or you could read it together. It might be a good place to break the ice.
Or try to find some other tool you can use to help you break the ice. That would take the focus off of you, per se, and place it on the tool you are exploring together.
My .02, fwiw.
Go ahead and go to the mts. Can you get a gf or 2 to go with you? Maybe you could plan something for an upcoming weekend with some friends. Remember that you are responsible for your own hapiness, and it sounds to me like you haven't been doing enough to take care of yourself.
