We've been dating a year now and he's really into the gym. I'm in college right now studying to be a doctor, so I don't have time for the gym. Before we started dating, all he did was post about about sexy girls are when they workout a lot and get that toned look. That's really bothered my our entire relationship and made me really insecure about my body. 

I'm 5'3" weighing a 110 pounds, so I am skinny but I'm not toned. My thighs and butt are where my weight gathers and I have a bit of cellulite on my upper leg, which I think is disgusting. He pinches my fartherly small pudge pack saying how cute it is, and all I can think about is how he likes the girls that have abs. I've talked to him about this and he says he loves my body, but as he goes to the gym all the time and gets flirted with by the girls that look like that it makes me feel even more insecure. I know he'd never tell me he doesn't like something about my body in case he'd offend me. It's so hard to feel secure when I look at him and he looks perfect. 

I can't stop comparing myself to what he used to say he liked. My insecurity is so bad that I hate taking my clothes off around him and try to hide parts of me. That really interferes with our relationship sometimes too.

I'm worried one day he'll decide some girl in the gym looks better and go for her. How can I feel more secure about my body? How can I stop being intimidated by his body and feeling inferior? Am I justified for how I feel compared to his previous preferences and his body?
