Well...my SIL is constantly bringing unhealthy crap (candy bars, other fattening foods, alcoholic beverages, etc) to my house and I personally think it's because she currently outweighs me by about 50 lbs and is trying to make me blow it. She has MANY insecurities and a lot of issues. I just figure she's insecure and wants me to stay fat with her...but I'm doing pretty well resisting most of the time.
My DH does ok, except that he "casually" offers me stuff I shouldn't have and sort of encourages me to eat it. Again, I think it's a bit of insecurity, because the other day he was like "You're gonna get all hot and then I'm still gonna be like this."
And do you know what I said?? I said, "Of course I'm going to get hotter dear, but I'll still love you."
LOL!! I'm so mean.

As far as the SIL goes, I just have to sort of "prepare" myself before she comes over and be ready for her "attack" on my health, lol...
