I think many of this H have to hit bottom (i.e. move out) in order to come back. If he moves out, OW most likely will move in, regardless of whether your H had that intention or not. I think the question to ask yourself is "If he moves out and starts living with OW, then comes back to be with you. Will you be able to forgive him (eventually) and move on? If the answer is no, may be he needs to know that. If you are willing to take this risk and let him move out to finally realize/decide that he wants to be with you, may be just let him decide for himself. When my H moved out for a few weeks (to be alone, but of course OW moved in with him), I innocently thought he really moved out to be alone to think about hte situation. I am able to take him back and I think the moving out really let him know what is it that he wants. It may work better in the long run because now he knows the grass is not greener on the other side. He knows he wants to be with me. Looking back now, if I know OW will be there, will I let him move out? I still am not sure. This is something you will have to decide yourself. on the trip, it's hard to say. What if you have time and suggest that you tag along? What will his response be? If he makes excuses, may be it's with OW. Not sure if you should confront. I think when H are in the fog, they are really so affected by OW that they don't know what they are doing.
