Common, it is simple. In Ed Sheeran’s voice ” I’m in love with your body
Every day discovering something brand new. I’m in love with the shape of you”
So, here is my view, he is discovering something brand new from his mistress while you are still holding on dearly to the old styles. He is no longer in love with your shape; perhaps you had a terrific shape when you guys got married, but now it is shapeless.
Now, the bedsheet you guys use together no longer smells like you, but that of his mistress. So now that you know why, hurry up and fix it. You can thank me later!
