Sex vent!

So my husband and i have been together for over 2years, at first like every new couple we couldn't keep our hands off each other. Fast forward to a couple of months ago we hardly ever have sex. He will masturbate everyday but doesn't want sex it's always me trying to start something sometimes it happens other times he goes he is too tired. It's really starting to get me down. We are away from home at the moment and you would think we would jump at the chance of some alone time but he would rather smoke weed and watch t.v. It is really starting to get to me. He knows I'm against him smoking weed but I just don't have the energy anymore to argue about it. The no sex thing is just playing on my mind. I hate him right now! Just needed to vent
