Dear Prudence,
I’ve been friends with “Laura” for 15 years and seen her through many crises. Last fall she lost her job and was evicted, so I invited her and her son to stay with us until she got back on her feet. Laura was a slob who never picked up after herself or her son, did the dishes, or picked up a broom. She spent four months surfing the internet on our couch, while I spent day and night cooking, cleaning, caring for both her child and mine, and working full-time (I was also pregnant with twins). When she finally got a job, I sat down with her to discuss a timeline for moving out, and she got upset because she was hoping to stay for several more months. I told her we weren’t kicking her out and that she didn’t have to leave immediately, but that my partner and I had to start preparing for our twins.
A week later we came home to find her, her son, and all their things gone; she’d left a generic thank-you card on the bed with her name on it. I’m really upset at her ungratefulness. She even told mutual friends that I kicked her out. We didn’t speak for a few months, and then when I tried to contact her, she didn’t return my calls because she was still angry that I asked her to find her own place. Through a mutual friend I know she expects at some point to resume our relationship, but I am no longer interested. I’m still hurt that she would end a 15-year-friendship after we housed and fed her for four months without more than a perfunctory “thanks.” I feel like conveying this to her would provide me with some closure. Is it OK to write her a letter telling her all this, and that I wish her well but no longer want to be friends?
