Am I being a Jerk? (longer than I thought it would be, sorry kids)

Backstory: FMIL is one of the most passive aggressive people I have ever met. She's NEVER at fault for anything that happens in her OWN office and she laughs everything off like a child. She also speaks in baby talk sometimes when she wants something which makes me want to rip off her head and vomit.

Anyway, whenever someone brings baked goods or sweets of some kind to the office, I tend to say, 'No, thank you.' (I like to stick to my 100-calorie packs if I need to snack) FMIL is always like, 'Ooo are you surrrreee??' I say yes. Then she'll make a remark about losing weight. Whatever.

The other day she said something about how much weight I lost, like 'ooooo wow, you look great,' but in Greek of course, so I pretty much ignored it. I've never been able to take compliments well anyway. Then she said something about needing to fit in my wedding dress. I said, 'No, my wedding dress fits and it looks good. I lost weight for me, not for the wedding dress.' She said, 'oOoo ok!' Ugh.

Today she put a box of chocolate cookies on my desk. WHATTTT THEEE HELLLL??!!??! I said, 'No, thank you, please put them on your son's desk.' She said, 'OoOooo oookkaaaayyyy.'

I am mad. I guess it's just her trying to be nice, but please leave me aloneeee!!! Stop giving me garbage food!

I know, I'm being a jerk. ugh. I have to just let these things roll off my back.
