Gaining

Struggling with her weight losd

After helping my girlfriend go from 10 stone to 16.8 stone which we both realy enjoyed doing she has decided to start slimming world, and I would always support her in any decision to loose or gain weight.
I'm Just having problems knowing that her big body will get smaller I can't feeder any more and weigh in's will be going in the wrong way.
Has any one had to come to tearms with this sort of thing? And how?
