I think that strength is something our MLCers both envy and admire. I also believe that they need someone strong to be there for them at the end of the crisis. The OP can't measure up because they are typically weak. They have been holding each other up throughout the affair, bolstering each other's belief that what they are doing is okay. One strong gust of reality and the whole illusion comes tumbling down.
A, I too have found a peace and contentment in being alone. I would like to have a sane and loving partner, but it won't be the end of the world if it doesn't happen.
