<human>: We have been going out for 9 months and have had a wonderful relationship. He makes me laugh, he's there for me, we can talk for hours, and I can see myself with him a long ways down the road.

But the one thing I'm letting affect our relationship is my self confidence. He follows girls that look nothing like me on instagram. He browses them when we're cuddling together and he makes comments on how nice their bodies are. In addition, he makes jokes about girls we see in public. Saying how nice they look or how I don't have the same goods as them. Of course I know he is joking but I'm having a hard time not letting it get to my self confidence.

These girls all are tall, amazingly fit, with decent size boobs and nice butts. I'm on the other hand as thin and short and flat as they come. Usually I'm pretty confident with myself and think I'm at a healthy place physically. It seems like such a petty thing as I'm writing it now but it's the little things that chip away at my self confidence. 

I've tried different things to get past this problem. I've acknowledged this problem is coming internally. I try turning away when he goes on instagram so I don't have to see the girls. I try telling myself that I am beautiful and my body is pretty great. I started lifting weights so I can look more loke the girls. I tried telling him how I feel about this. 

But no matter what I do, it doesn't seem like it's working. My boyfriend tells me I'm beautiful and my body is perfect. I try so hard to believe it. I really want to believe it. But I just can't when the next thing he does after telling me that is go back to browsing through the pictures of girls. 

I feel like my self confidence issue is eating away not only at me but also our relationship. How do I get over this issue? What are some ways to become more confident in myself? I just want to be a more confident person.

Could you distill the essence of the text into 1-3 sentences?
<bot>: my boyfriend has a different preference for body types than mine when he is on the internet. I want to know how to be more confident in myself so I can let this stop affecting our relationship.
