I am currently living in a 2br/2ba apartment that I will be moving out of at the end of July. Two of my friends (who live 4 hours away) are possibly moving to my town for college, and I am planning to live with either one or both of them. A girl I met about 6 months ago wants to move in with us so we can have a 4 bedroom apartment. She caught me off guard when she asked about it and I don't remember what I said, but I feel like it is not my place to decide to take in a 4th roommate, especially since the other 2 girls have never met her. After spending more time with her, I really don't think I can live with her! However, now the other two girls may not be moving here after all. I am perfectly fine with the idea of living by myself.
My question is: How do I tell this other girl I don't want to live with her? I think it would ruin the friendship, but I am afraid telling her would too. She is extremely sensitive and I know whatever I say will make her angry- I am just looking for the best option.
Please help!
