I actually had a very easy time losing weight, I think it's because I changed my diet for the intention of being healthier, not the intention of losing weight, that was just an added bonus ;p
I never get fast food cravings of want unhealthy foods realy badly, so it was no struggle,
but good for you on your weight loss so far! And be happy for him too, plus you can use him as motivation
And be happy that you have a bf, too -.o
