long distance relationship😬💦

I'm currently in a long distance relationship with a guy I really like. we both send nudes to each other and we really enjoy each other's company. I feel that he really isn't interested in me and he's only there for nudes 😬. I've also began suspecting that he is maybe getting nudes from other girls also. Everytime I just want to talk to him about random things it always turns into something sexual with him or asking about nudes. usually I am horny along with him but sometimes I'm just not in the mood for it. 😫 what should I do? I think it's only physical attraction with this one. he is also a white boy and I'm a black girl.
