Up until recently usually one of us ended up on the sofa but we bought a new bed for the spare room a couple of weeks back. The main reason is DP's snoring, I just can't hack it especially being pregnant again and with a toddler, I really need my sleep. He doesn't seem to mind and I don't mind but it seems kind of odd. We don't do stuff that often, he has a very busy workload and often stays up late working etc and we both usually end up too tired to do much anyway.
I know its not the best solution for a married couple but is it weird?
