My OH came in a few weeks ago and said "why don't you ask so-and-so for a few tips, she's lost loads of weight."
Now there are two things wrong with that... first off, so-and-so had hardly anything to lose to begin with, secondly, I AM losing weight... over three stone so far!
Sometimes men are just insensitive, but it sounds like your OH has a real chip on his shoulder about this. Sit him down and calmly tell him if he doesn't want to support you on your journey then he doesn't need to be there for it. Life is too short! But on the other hand, life is just too damn long in the wrong company.
