why can't you ask him to leave? Worst case scenario is that he refused till he's ready, which is what is happening already...
OR ask your L to contact his. In some states there are semi automatic restraining orders upon request. Even if only for 10 days...
I don't think either of these ^^ options are worse than just letting him remain indefinitely.
