It Just Straight out Sucks!

I'm just going to say this... I hate eating at my moms house! Because my mama got some good cooking! I mean the type of food were you just want to lick the plate clean type cooking! But she knows I'm on a diet and she keeps taunting me by wavy food all in my face. Saying like "you know want thisssssssss!" or " you know you need thissssss!" She is not making this easy for me and I ended up gaining back 2 to 3 pounds. Now that doesn't seem like much.... but I can't allow my weight to slip on me like that because that’s how I got into trouble in the first place. I didn't pay attention like I was suppose to and I ended up 5 pounds away from being 200 pounds which scared me. I'm 146 right now and I want to stay in that range but I don’t want to hurt my moms feelings thinking I don’t want to eat her food anymore. I still will but I just don’t want to eat a plate full of food that would be able to feed 3 people! I can’t down all that like I use to so it has to be in portion. Do any of you have the same problem when it comes to food and family?
