Long distance insecurities/drifting or overthinking?

I’m feeling a bit overwhelmed lately. My boyfriend seems less clingy and maybe that’s just the honeymoon phase ending and us just getting used to each other but it makes me anxious because anytime this has happened in the past with previous relationships it’s ended. He’s a lot different than other relationships so I know I shouldn’t compare him to them but it’s just really hard not to be anxious. We are long distance but he just used to seem a bit more interested and I just feel like we talk less now and when we text it isn’t very full of convo... I could just be overthinking it but I’ve also felt insecure lately because he is friends with a lot of drop dead gorgeous girls and I don’t feel pretty enough for him.. any advice helps.
