I'm sure you've heard this before, but it bears repeating: Everyone is different! Believe me, I know how discouraging it can be knowing that some women can use up all of their weekly points, plus their Flex points, and still lose, while you seem stuck. But everyone's body is different and everyone's metabolism is different, so everyone loses weight differently.
The important thing is that even after a "not-so-good" day (or two, even!) you're picking yourself up and moving on. I don't remember who said it, but there's a famous quote that goes something like "Failure doesn't lie in falling; failure lies in staying down." As long as you keep getting back up, you'll never fail. (Even if it takes longer than you want it to!)
As for the comment your husband made: sometimes trying to lose weight can make us extra-sensitive. I'm sure your husband wasn't trying to be insensitive or make you feel like you *need* to work out more. He was most likely trying to encourage you to work out as much as you can; and maybe he thought that with his mom coming, you might miss out on some of your workout time. I'm sure he didn't mean to come off as insensitive. But I can certainly understand feeling as though he meant something totally different; I get that way too, whenever someone (usually my mother! *L*) makes a suggestion about how I can fit more workout time into my week. I immediately go to that "OH MY GOD, you think I need more workout time, I must look like an elephant!" place too. *L*
Just keep looking straight ahead and charge on. You will reach your destination, even if it takes a little longer than you'd like.
