I think you answered your own question about how it happens--eating what your boyfriend ate. Been there, done that. Take back your healthy habits and stick to them.
The pictures are a great idea, or even taking a measurement each week or month, like waist or thigh. Trying on clothes to see your size change is fun. Just paying attention to what you're doing helps a lot and it sounds like you are doing that. Don't give up--you'll figure it out.
