YR - I too had an intuition, and hesitated to raise it until you did This is not a criticism, but I realised that there was consierable pressure on your h to return home when he did. Understandably you had had enough and sensed, rightly that he was in a place where he was prepared to respond to the pressure and come back. I can remember how anrgy you were at times. Also, as I recall, it was impacting badly on your daughter.
I now realise that they have to fully complete their journey without pressure to return, otherwise as either [I think] Snodderley or HB wrote, if they return before they are ready they will 'run' again. Doesn't mean that they will actually go, but re-enter breifly some of the late stages of MLC in order to finally close the doors. I think this is dealing with unfinished business in his own way, and you are going to have to let this happen and not fight it.
I know you must be bursting to say things, but remember the MLC rules - no r talk. You will make it. You know how to button your lip as all MLC spouses do.
YR he has to finish this. He came back before he was fully baked. I am on your time scale and my never came back He is still in lala land. It could be worse!
Hugs
PS Query to HB - I know you don't advocate throwing them out, and I agree, but what happens if, as many do, they decide to leave?
