Just that really.
Not something we have ever considered. He's home and not working for the two months he's home. If I'm on a day shift I have to be up at 4:30am. He wakes up with my alarm, gives me a kiss. Sometimes helps me get my lunch ready for work then goes back to sleep.
If you get up early and your DP/DH doesn't need to be up would you sleep elsewhere?
I find it odd people do this. But maybe it's because we have enough time apart anyway as he works away 2 months at a time.
