Sounds par for the course with alot of sitch's here....don't beat yourself up about missing your chance, if she really wanted to work on it she would...she was being the typical WW....
Don't let the ride continue...get off and keep working and living for you!! The waves of good and bad will continue but like you have experienced they will get shorter in time. ;-)
I remember the days when I couldn't even work because I could not concentrate on anything besides my W...ugh..painful painful days...I wouldn't wish on anyone. But I truly can say I am stronger and I am trying to focus on the positive things in my life.
You will be ok BSB...with or without her, keep busy and do things that you enjoy!
