Hang in there, GWS. You will get some great advice here.
I have only been DBing for about two months and have learned so much. My wife is still in the house and we have our good days and then she is the alien again for a while. You have to back off and not let her moods/actions affect your mood. I am always reminding myself this and sometimes backslide. It is a constant battle but you can and must do it. Let her be how she is right now. You work on the new you. Don't look for approval from her.
Even though it feels like you're trapped and running out of time, one of the most important things to work on right now is patience.
