So exactly why should you need closure? And why should you want a friend in the future who could turn back to drugs and a husband at any moment?
The minute that lease is up, get your things, move elsewhere and don't look back. You don't need a friend, a lover, a wife, a partner or a playmate who is heavy into drugs.
You also better hope the police don't follow her home before April 30th because if they do and find illicit drugs in your unit they will arrest you as well as her. Of course, you can convince the judge later you had nothing to do with them.
There is just no reason in the universe for having anything to do with this lady. You will never be able to trust her...until the end of the world. Hold no hard feelings toward her, forgive her and let her be on her way. Wouldn't it be just a joy to renew a friendship in the future with somebody you had to put a lock on your bedroom door so she/they would't break in, steal or move your belongings to raise money for drugs???
