Back here again - why oh why?

[~¤DG¤~]

I am shocked by what your C said and I don't think I would go back to her either.

Your M is worth saving, but it has to be both of you. You can't carry all of it on your shoulders.
Continue to DB for YOU.

"1. Fix yourself
2. Fix the marriage
3. If the M does not get fixed, fix yourself to ensure you don't ruin the next R before it even starts."

I couldn't agree more with this statement. A lot of times people leave one R and jump into another one thinking that all the previous problems/insecurities/issues will disappear along with the relationship.
I have learned first hand that nothing could be further from the truth.
