<human>: I've been dating a great girl for three months. She has many qualities I really like, but one thing bothers me. She owns a home and wants to help unfortunate people by letting them stay with her while they get back on her feet.

For instance, she's frequently told me about how she wants to let a former foster child [20/m] from a program she volunteers at live in her home for free.

I think it's great she volunteers and contributes to the program where she meets these young people, but her breaking the personal boundary of bringing someone into her home would keep me from getting more serious with her.

I've only been dating her for three months, and I don't know how much is appropriate for me to be involved. When she asked me, I told her I don't like the idea.

My question is, is it appropriate to tell her that it's a deal-breaker before she lets people move in with her? I feel like I would be being passive aggressive either way.

If I tell her I'd break up with her now if she did it, it would feel manipulative. I also don't want to try to change her - she might say no to this person but always want to do this at some point.

On the other hand, I wouldn't want to continue the relationship if this is the kind of thing she wants to be a part of her life.

Can you give me the gist of the text in a nutshell?
<bot>: Girl I've been dating's desire to help others by letting them stay in her home is a deal breaker, but I don't know whether it's appropriate or how to communicate this.
