You didn't mention your state and details may matter to those who know the technical ropes better.

I suggest you get some immediate suggestions from a nearby womens abuse/shelter advocacy group if you can find one.

Seek careful wording of the PPO......in some states a PPO might keep you IN there and him out until the dust settles a....but the details matter ..again...try to use counsel.

In some states it can take a pretty long time to evict a tenant who exercises her rights well. But beyond that's its a pure guess.....

In general an eviction notice is but a first step....and a long way from the final step.

I agree with Knowitall that ultimately you are not going to be there forever....but it may take BF more than a few weeks to get there

My suggestion....hang in there at least until you can get some reliable help....or information
