My boyfriend sleeps so weird it takes everything out of me not to wake up and slap him sometimes in the middle of the night. but for real explain to me how he takes up 3/4 the bed has one knee all dug in my back and one elbow too and almost every hour I wake up tell him to move and in an hour he's back to the same hurtful ass position. gonna start sticking my knees in his back grrrrr
