Something's gotta give! Where did she come "from" that she's now got nowhere to go? I think you're beginning to get a reputation as someone who won't say no ... Is there any way you can give each "temporary" person a time limit? As in, "I love you, but I can't have you here forever, for my sake and your own. You can stay for (a week, two weeks, you pick the time) but then, as much as I love you, I'm gonna have to a. charge you rent (significant enough so it'd make a dent in your expenses and be a disincentive to staying) or throw you out."
