It's your call. No one can make that decision for you, or tell you it's right or wrong. You decide what you want, and then try to get it. If you want a restored marriage, then you go for that. If you want out, you leave. However, be clear in your own mind what you want. If you are not clear, don't make any decisions. Just linger in the uncertainty. That's hard, especially for someone who is used to control and getting results fast. If you want your W back, this is going to take a long time. It might not succeed. But, if you have any shred of desire to try to make it a go, then you must hang in until the very end. However, if you are are sure you can't take any more, then you should leave.

I'm leaving for several days on a business trip. Take care, and be good to yourself and to others. One day at a time.
