Well, I am new to this but I find it very helpful to my own boundaries about what I will do if I happens again. I am also working on a legal and financial plan with my long-time accountant and consulting an attorney about post-nuptials and other protections for me and the kids should it happen again.
On the whole, I have come to accept (painfully) that I won't ever have that kind of trust again. My marriage is going to have to be very present-oriented and enjoying it in the moment. Sometimes I think it is like being married to someone with a very serious illness who could die or become gravely disabled at any time.
