Accepting my own inadequacy

I feel like I’m reaching the point of just accepting the fact that no one will ever love me or respect me, even sexually I’m just a toy for his pleasure even though I have restless genital syndrome so it would be nice if he would make me orgasm at least once in a while since I’m literally in pain down there. I feel worthless and empty and I don’t know what to do anymore. I have zero friends, zero family, only a boyfriend who means everything to me and I mean nothing to him. It’s about to be our one year anniversary, and he’s still never told me he loves me. He claims he just wants to be sure but after a year, I think, someone should know. He just wants to keep me around. Sometimes I just desperately want to give up.
