Your friend is (to risk a double entendre) flirting with disaster.
I know this is difficult for you -- how can you manage to hold onto a long term friendship with someone who has decided to chuck the value system by which you both are secured? Your friend is seeking to build a support system for doing something she knows is fundamentally wrong, but is not concerned for how this might compromise your own values. It would seem she just wants enablers.
My sister-in-law has shared with me how her own best friend, bosom buddies since they were in elementary school, betrayed her husband and walked out on him and their children. It really tore my SIL up to find that her best friend could do that to her own family.
