Dear @Bubbles3,
I admire your will to make your marriage a happy one by sacrificing yourself for it.
Please forgive my sarcasm in the last sentence, but are you really willing to sarifice yourself to the point of complete annihilation, for the sake of pretending a happy life?
I fully understand what you are doing ( I felt the same for years ), but any mental disorder does not play by the rules we would like to create to lead a normal life again. You admitted it yourself, you pretended to be his happy wife, but inside you still struggle, fight the same issues and feel alone, lost and eventually without hope. I do not wish that for you.
It will only be a matter of time before the facade of your deception begins to crack and crumble away - and this time at what cost? What about your kids, they need their whole mum to look after them, be there for them. Mum's are the glue of life, keeping the pieces together that create a solid bond.
Is it fair to the one that really need you as a whole, when you begin to withdraw, have emotional outbursts of anger or rage, depression, apathy?
I implore you, do continue on your road to recovery even if it means to make tough decisions.
I leave you with a quote from a movie: " But it's only on the brink that people find the will to change. Only at the precipice do we evolve."
