Is it me?

Why is my husband always finding excuse to not have sex? I'm tired I have a headache i need a shower I don't feel good tomorrow night I promise.... Fuck you I fucking hate it .... Makes me feel like he has no interest in me whatsoever I'm lucky if o have sex 3-4 times a month and I'm a very sexual person... We went at it like rabbits before up until we got our own place now it's hardly ever.. I just want to punch him right now
