I have a roommate that moved in with me is was suppose to move out on June 30 but is trying to move out in feb what should I do

There are too many different variables to answer that question as it currently is asked.  It depends on numerous factual issues, such as what the terms of the lease state.   You should consult a local attorney because a local attorney can review your lease and determine what steps are appropriate.
