When I was growing up, both sets of GP had separate bedrooms and it felt like it was completely ok. I never felt it was strange, my nans on both sides had their bedrooms and grandads had their own separate bedrooms. When I met DH, his DM & DSD also had separate bedrooms, and his Ddad and DSM also had separate rooms.
Over the last year my own DP have decided to have their own separate bedrooms. Again, this is my normal and it is something that I have lived with all my life. No marital issues in any of the relationships (obviously that I know of)
When my DM was going through the process of turning my old bedroom into her new room I mentioned to a colleague that I couldn't imagine there being a time when I would want to sleep separate from DH. She looked really shocked and said she'd never heard of anything so ridiculous as a happily married couple sleeping separately and that there must be marriage breakdowns. She said that would be the only reason to sleep separately and have separate bedrooms.
She then went on to take it a bit further and proceeded to tell all other colleagues about the 'weird' setup in misskittys family. I was sat right there.
So my aibu is: is it 'weird' to sleep separately? It's not something I'd really thought too much about until it was mocked and I was made to feel it was strange.
