<human>: I've been with my wife for 18 years, married for 12.  We have 2 great kids (8 and 5) and get along great, but she has completely let herself go (IE - gaining weight and not giving a damn).  This is completely killing her energy levels, her libido and (I hate to say it, but) my attraction level to her as well.  I really must sound shallow with that last part, I still love her with all my heart, and I want to help her.  She's sending herself to an early grave the way she's going.  She pays lip service about wanting to do better, but never actually does anything.  I've asked her to workout with me, but she says she couldn't do what I do (I'm doing T25, and there is a modifier), so I offered to just go for walks every day, she says no time for that.  She says she's stressed because she's working (teacher) and doing her Master's at the same time, and I know that's a lot, but I did the same thing 3 years ago and wasn't this stressed out about it.  

I just don't know what to do here, I feel like if I say something, I'll get the "so you think I'm fat" response and she'll just shut down or go stress eat some more.  I'll gladly accept any suggestions on how to approach this topic and see if we can get this turned around.  Short of having an intervention, I don't know what else to do.

Can you provide a brief overview of the text?
