What's wrong ?!?

So I have been married for 6 years .. My relationship with my husband at first was full of love like it should be.. Now he's distant & I KNOW FOR A FACT he's not seeing anyone,but he's just like in a "whatever" relationship  I know deep down he loves me but I would love for him to show me with actions ... I do everything a wife should .. Take care of my home nd my family even his mom...  Recently I've been starting to give up on him... What should i do ?!  I've already tried everything even confronted him but like I said ... He's still in that " whatever stage"
