Thanks for your reply.
There is a very helpful thread on the forum today that is closely related. It is:
Topic: R'ing and Staying Married are not the same things
Among other topics, that thread focuses on the question: "If you are *staying for the children*, do you really believe it is better for them?"
I agree this is an important question, but not one that I can handle right now. I am just trying to understand what my options are before I decided which is best.
So maybe to rephrase, my question is this: If you stay together but don't reconcile (e.g. no sexual relationship) how can that actually work in practice?
