My Side of the Bed

Is it strange that after almost three years of not having a significant other sleep next to me every night, I still sleep on "my side" of the bed? I have a large king bed, and I just can't bring myself to sleep on the other side. It feels toxic. Treacherous territory. A waste of a good portion of the bed. When The Older One crawls into my bed in the middle of the night, her little body fills that big empty spot.
