Help, I'm losing interest in my husband!

Lately I've been losing interest in my husband we been married for only 2 years and I just don't want to be around him I feel as if I'm his mother. We aren't having sex at all the last time was a month ago. Before we got married we had a crazy amazing sexy life but now it's like he just doesn't care about it. How do I get him to act like he once did I don't believe in devorce but can't life like this forever.
