UKnw.. I think everyone can relate on some level. We all want to be the best we can be for our partners, and if we see them being more successful or more motivated than us, it can be challenging. Just keep in mind that just like your weight experiences are different from your girlfriend's, the way you motivate and follow through are different as well. IT doesn't mean they're better or worse, just not the same. Also keep in mind that just because you're taking longer to get to your goal, it doesn't mean that your success is "worse" than hers. You're doing what you can, when you can, and like you said, it's wonderful that you've gotten this far!
