I think that instead of worrying about his feelings about this, you need to focus on YOU and your health and wellbeing. This isn't about him, it is about how you are feeling about yourself - and it sounds like you are hoping and waiting for the encouragement from him that you aren't going to get - it oculd be he is afraid to say the wrong thing, or maybe he just doesn't know what to say.

Once you get to your goals, and once he sees how committed to this you are, he will come around - in the meantime, this is time for you to be selfish and take extra care of yourself - figure out what makes you feel good, and do it - for me, it was perfume. I have been a bit down this week, and as a single mom, money is typically tight, but I splurged a bit this afternoon adn bought a bottle of perfume I have wanted for a very long time as a reward for keeping to this way of life.

you will get through this little "blip", and be right back on track
