<human>: I am 180, she is probably around 250 now. It used to be the reverse few years back and we are going in opposite directions in terms of fitness. We have a great sex life (1-2 quickies a week, 1 long),  have weekly date night, both work at jobs we love, and have a stable income and household. We also have a daughter of 7.

I never mentioned anything. She has been saying over the last 12-13 months that she needs to lose weight and thats her goal. So i asked her what should I do or how can i help. She said "don't say anything or push me, let me do it on my own." 

Thats what i've done so far.

Last night, she went up the stairs to kiss our daughter goodnight and was out of breath. I have to help/do something. Only, I don't know what or how to do it.

Need help. :(

Can you provide a brief overview of the text?
<bot>: Wife gaining weight and increasing. Don't know how to tell/push/motivate here without shitting on an otherwise good life we have.
