So I have a friend (25F) that came back from Costa Rica. She asked me to pick her up from the airport and I agreed but when I went to pick her up she asked me if she could stay with me (26F) and my boyfriend (23M) for two weeks because her mom is pregnant and she wanted to make sure she didn't have the corona virus. I asked my boyfriend and he said yes. Well that two weeks turned to six so I told her she had to go home. When I get off of work to take her home, she says her stepdad won't let her come home because they had a falling out. She waited to tell me this until it was time for her to go! She doesn't work so she sits on the couch all day, she doesn't help clean, doesn't have money. Her only option is to go to New Orleans with her aunt but she doesn't want to. What should I do? I'm getting annoyed and it's going to cost us this friendship.
tl;dr: friend asked to stay with me and boyfriend for two weeks, and now it's been seven and she won't leave
