I've seen that feeling from my wife. It means your 180 is working and he's reconsidering the A. You're now equal to or the slightly better woman. Whatever you do, do not get into a fight over the next few weeks and you'll see that look a lot more. Remember "you were friends first and H and W second".
Now he may "blur" the good times you had the next day and forget what he's said or promised. This is just him coping for showing insecurity and opening up to you, so you can expect a blur or ignoring to happen later. Don't sweat hon, just "act as if" and still be kind. Also get him do what he can that same day like going out to luch together or looking at fish at the pet store.
For motivation try the $1 game. Give yourself $1 for every day of good contact, and take away $2 for everyday of bad contact. So long as he isn't angry or arguing with you I'd consider that a good day. I'm up to $22 so far
Look up Eat Stop Eat for weight loss. You can get it free or pay $40 I think. I lost 40+ lbs since June and with intermittent fasting I lost more fat than I ever did with cardio or low carb diets.
