Agree with the people saying you need to stop being a martyr, stop assuming your daughters will be very distressed at you popping a bed in the 'playroom,' and stop thinking that it's a dreadful thing to do in your marriage to sleep in separate bedrooms.
Some of the happiest marriages have couples sleeping separately. Sleep deprivation is a form of torture, and no-one should have to tolerate it. Annoyingly it's almost always WOMEN who are tolerating it, and feeling ashamed and embarrassed at the thought of sleeping separately from their husband.
For some reason, we are conditioned into believing that married couples must ALWAYS sleep together. I think it's old fashioned, out-dated bollocks. I cannot think of a single advantage to sleeping in the same bed as someone else. You get hot, he kicks and rawls about, he snores, he farts, he coughs, he steals the duvet, and it's pretty shit most of the time for many.
I don't know whose idea it was for 2 full sized adults to share a 4 foot x 6 foot space anyway! I think it harks back to days of old where people slept together for warmth, and because of lack of space.
The middle classes (and upper classes) have almost always had separate bedrooms, and sleeping together was traditionally, only for the poor.
If you have a spare bedroom, for goodness sake make it yours! If he doesn't like it, tough bollocks. It's OK for him, HE is getting sleep. You're not! All too common in marriages/ relationships for the woman to be the one suffering.
