Hi Masterofart,
Oh my! That is a lot in a first year of marriage! How long were you together before you got married?
Check out the lessons to the right of the board.
They will start to help answer this question of "how am I supposed to act?" In time you may want to dive in deeper and share examples and members can share ideas about what to do/not do for all kinds of situations.
So has the marriage counseling started? How did her getting diagnosed come about?
I am sorry for your pain related to the affairs and accusations! I can relate to how painful and disappointing it is when someone you love can be so difficult to be with.
wishing you peace, pearl.
