Oh. Well, can I just say that i've been mega moody as well - and when i was out having tea (i'm SS+) I was in a good mood (because I was eating), my OH said I've been horrible to live with this weekend too. I think it's because it was Easter, TOTM (i'm a moody cow then anyway - so you can just imagine how evil i was this weekend), and just generally feeling fed up.
It's hard to know what to say - but definitely don't give up! You've either got to make a real effort not to be moody (in front of him) or he just has to accept you the way you are for a few weeks/months. It's alright for him to say he'd rather you fat and happy - but can't he see the bigger picture? There are so many reasons why i want to lose weight - i'm not getting any younger (41 this year!) and i don't want to have achey joints and to find it difficult to walk up the stairs. Would he like you fat, happy and not being able to walk very far? Great.
We all have to put up with our OH's little habits that probably bug the hell out of us - but we live with it - because we love them.
He'll have to put up with a moody poody you for a little while - for the sake of YOUR health and wellbeing.
I want to say selfish sod - but i wont. Oh i just did. Ooops.
All the best lovely, and come on here and be moody with us other moody cows.
