feeling like I'm not good enough

I feel like crying right now. I want my boyfriend and he doesn't want me. he says he's too tired. ive been having some self image issues and I keep having dreams that he will move on to another woman who is better that me. but there are times when I feel like he doesn't want to have sex but does it anyways befuase I want it. I feel like bawling. what is wrong with me? am I not good enough or am I just over thinking? becuase I feel like I'm not good enough and I'm not overthinking
