I feel like my bf doesn't find me attractive

Julia
I just want to start off saying that I used to have a really bad self esteem problem a while ago but for the past year and a bit I've been feelin great being me so how I feel now is just confusing me, anyway,
A while ago my bf told me he likes pale thin girls with dark hair, I'm a well built kinda tanned, dark blond and I didn't think of it much till not that long ago, when I realised its like he doesn't want to see my body anymore (we live far from each other so we'd mainly just send each other nudes etc) he stopped asking for them and I mean I didn't love it but it made me feel like I'm wanted. I told him that it makes me feel insecure about muse and he can clearly see that I'm bein really demotivated about how I look and he promised me a few times he'll start complimenting me more but he never does. It makes me feel so unwanted bc I know I'm not hit type. I caught him watching porn once but I'm pretty sure he still does he just deletes the history on his phone, what should I do?????
