admylin, regarding your plan B - well that's what we did, and for us it has been surprisingly difficult. I thought it was the perfect solution, he gets the job he wants, me & dc get the stability of staying in our home. I thought, he's often late home, the kids only see him for a short while each night, if at all. No problem. I'm not very dependent, am used to coping, do most things around the house myself anyway etc etc.
So I was surprised how hard it has been for all of us. The boys have really missed their dad, but at same time, some nights refused to speak to him on the phone, which dh found very difficult. If the train was cancelled, and he could,'t get back when planned they were disappointed. It was really hard to cope with him coming back tired (read grumpy) and balancing this with needing to do stuff with the kids etc etc.
From our pov, relationship-wise, it has been bloody difficult. On the one hand I often felt I didn't miss him, and felt we were really drifting apart. I felt it was very dangerous actually, esp long ter. When he came back I don't like having to share my bed again. And if there were issues, it was really hard to talk about them, as dcs there till say 8.30/ 9, then didn't want to spoil our 2 hours a week alone by having heavy discussion/row, so things brewed or went left unsaid.
All in all, it was much harder than I anticipated, and for this reason finally, reluctantly agreed to move after all.
Sorry for waffling on, but I went into it really positive and confident it was a brilliant solution, but had a far greater impact that I thought possible. You really need to get dh to agree to next move being UK or something. It's a bit of a rock and a hard place - disrupted kids in new town vs. daddy being absent, but I think the latter is the worse option of the 2. I hope you (and I!) can convince our dhs to stop this carry on
Says she, who, is moving in 2.5 weeks, full in the knowledge that in max 3 years we have to move again.
