I'm so sorry that you're in this position. As uncomfortable as it would be for you, you might rethink your attitude towards telling the women you need some space. Remember the idea of putting principles above personalities. Recovery is much, much (a million times) more important than a few women.
Asking for space in a kind, respectful way is setting a legitimate boundary and a huge sign of respect for yourself. I see it as you taking care of yourself and an incredibly healthy thing to do.
