Randy: She may be sexy to you, in your eyes her weight may be fine but unless she embraces herself and loves who she is she won't feel sexy trust me! I've been there and especially as we age and things get "displaced" it may be hidden by clothes but when everything is off oh boy our insecurities come rising to the surface!
As for the ILY - love language issue in my opinion - its a Love Language for you but necessarily for her. She feels she expresses her love to you in other ways - one huge one by moving back home.
