My wife's friend evacuated from storm Dorian and moved into my house for a few days, but now I am ready to kick them out since the storm passed.
Why do you want to do that?
I'd like to kick her out, we've been talking about the situation and things we were going to do.
That sounds like a difficult situation. How does your wife feel? Maybe you both could talk to your wife's friend and explore a path and timetable for her to get her own place?
My wife is okay with it and she wants us to do it.
Even still, if you suddenly kick this person out of your home she may be put in a hard situation. You should consider her feelings in this situation.
