I Married A Fat Bitch

It’s a girl I’ve renowned for a long time, I went for a few years without seeing her and now she’s place on about 60 pounds. I want to help her lose the weight because I know she doesn’t like it. I like the ancient her as well. Please don’t disturb telling me i’m shallow, cause she wants to lose weight too, from what her friends tell me, but she won’t talk to ME about it. How do I start the conversation?
