I used to cook for my partner every single night up until 10 days ago when she started Cambridge too!
The first few days were tough as i was getting into ketosis and everything was a temptation, but i stuck to my guns, made the dinner and then took myself to the bathroom and had a loong bubble bath with nice bath bombs, candles etc!
The temptation DOES go. I'm on week 17 now, 4 stone lighter and so so motivated!!
