4 years together has low sex drive

So my boyfriend and I have been together little over 4 years it’s been like two weeks we haven’t had sex is it that he’s getting over me ?? I don’t like asking for it cause he always tells me idk how your sex drive is so high , I feel like he gets annoyed ?? Lol then I get disappointed idk if I’m just not as hot anymore the first 3 years this wasn’t a problem idk what to do anyone else going thru this ?
