Still a hypothetical situation really as partner and I wouldn't be seriously looking at moving in together until maybe the end of the year, but looking for opinions anyway. He's currently in a 2 bed flat (rented) whereas I have a 3 bed house (owned with mortgage) and he knows I never want to leave here if I can help it. He pretty much stays round here every night unless one of us has plans until late.
He separated from ex wife about five years ago - they have a DD 9 and DS 15. Acrimonious split and still don't get on well, there are often times where she will say he can't have the kids (sometimes will say they have plans when they don't, changes days/times last minute etc). At the moment he sees them a couple of times a week - they don't stay over due to the logistics of getting to/from school and work the next morning, the times don't add up and obviously at his they would need to share a room.
I WFH and would need one of my bedrooms to stay as an office as there's nowhere else in the house to set up properly. The other room is a proper spare bedroom with bed, etc. But obviously at that age and opposite sex the kids couldn't share - and they couldn't have one bedroom each - but obviously right now they don't stay over anyway (and don't ask to) - but what if that changes?
Would it be horrendous for him to keep seeing the kids, taking them out, etc. and then not stay over? There would be a bed for them, just they couldn't stay both together unless one stayed on a pop up or sofa bed (we could fit one in the kitchen/diner I suppose).
Or do I need to give up my dream house and accept we would need 4 bedrooms?
