Not getting anything!!

Help, recently I've been catching my partner watching porn while I'm at work. I start work at 6am every morning and he has an hour at home until he starts so that whole hour he watches porn. I NEVER get sex anymore because he is too tired or can't be bothered. I'm so sick and tired of it!! He would rather watch porn than have sex with me wtf do I do? I'm getting to the point where I feel like leaving because this is just so disrespectful, it is making me feel like I'm absolute shit and not good enough!!
