Should I leave my Christian husband?

I am a 28 year old woman, he's 29. My husband recently converted to Christianity around two months ago, and our marriage has been going downhill ever since. It's as if he's a completely different person, not the man I married. I've never really had an issue with religion until now that i've witnessed firsthand just how much damage it actually causes. He won't even sleep in the same bed as me and we often fight. I feel betrayed and trapped. I desperately need some advice.
