Sigh

How is it so easy to feel you are eating correct portion sizes, only to find out you were way off?
For the first time in a long while, I decided to count calories while at my fiancees instead of eye-balling the food and making healthier choices. Somehow I thought with all the healthier choices I've been making that I wasn't doing so badly on the weekends. I was W-R-O-N-G. On a whim, on Saturday I decided to put in my calories for the previous evening's meal after all.  His mom had decided to cook, and made what she calls hot dog casserole, which is bow-tie pasta, cut up hot dogs, onions, diced tomatoes, corn, and black beans. Let me just state for the record I have found a new hatred for all pastas and grains for one simple reason: the measurements are all dry. They are dry with nothing on the package indicating what 1 serving dry equals cooked. I ended up spending 45 minutes trying to find out how much bow-ties cook up to, and realizing that between what was served to me [a portion equaling the hugeness of my fiancee's who definitely eats more than I do normally, while she had something much more proper.] and the seconds I had because I was still hungry, and at 200 calories a serving.... 1200 calories. For a meal that still left me feeling hungry.
I was horrified. And annoyed. She feels she is eating more healthfully, and while she is for her, she still isnt paying attention to things. She also professes a hate of calorie counters, that she forget to use them and she hates feeling obligated to write everything down. I hate them when I realize I've overeaten when I wasn't trying to and read the label yadda yadda...
So I think I may have found the culprit. 4 nights out of the week [even when I do a majority of the cooking], I'm being sabotaged and sabotaging myself. 
I know this sounds like the biggest duh, but I guess there were a few baby step back to the path of health I forgot I needed.
I do think, on a off-topic, that my mother may kill me if I buy anymore tea before finishing what we already have. But flavors!!!
