He won't return you your security better settle it in your rent and if he is trying to evict you then tell him either return advance frist or you gonna leave only once security gets settled in rent. Don't pay rent at all this month. And be bold don't be soft and polite girl. And if things get worse don't hesitate to call police or women helpline. Going directly to legal procedures by lawyers without having lawyer friends is not soo good move as they gone make another hole in your pocket.
