I took a couple of years before filing for the D. My H moved back once but it did not last. OW had him firmly in her clutches. I did not stand a chance.
I think it is best to try to work things out and give it your best shot - especially if there are kids involved. It is far better to look back and know you did everything you could and be able to tell your kids that you tried hard - because they were worth it than to divorce quickly and always wonder what might have been.
