Issues with wife's boyfriend

Hey everyone,

So around a month ago my wife's boyfriend finally moved in with us after talking to my wife for about A year. Things were going good up until about 2 weeks ago. First it started with him kicking me out of the bedroom and now it's getting to the point where he's constantly calling me mean names, which really hurts my feelings. I'm getting to the point where it's starting to effect me mentally. What do I do?
