What to do about my Cancer Woman?

Hey everyone hope you Cancer women can shed some light on things for me.

I recently started dating a Cancer woman and true to most of everything I read (positives)
she's talked marriage, kids, wanting to be engaged by next year. Which are all things I
might add that I'm totally wanting and want with her. I'm an Aquarian and so I walk a little trepidly
and wait for signs that she's not perfect for me. Mainly if you've read some of my other questions, because
I came out of a devastating relationship with a Virgo whom I thought was going to be it for me.
Hence, the reason for ultra caution.

Well the ball dropped, she's mentioned that an ex-boyfriend propositioned her to, not to sugar
coat things, launder money across the border for $ 3000 cash. Now, I know that stability and security
are a HIGH priority for her and she agreed to do it, even at my disapproval.

It basically turned into, I'm doing it anyway and there's nothing you can say to change my mind, even
at the cost of our relationship. Although I said I'd give her the money, she doesn't want to accept it.

I feel the more I try and say that its wrong the more rebellious she becomes and brushes it off as this is
who I am, and I just want you to support me even if you don't agree. I don't know if I should just live
and let live even if it goes against everything i believe in and HOPE she makes the right decision or
just end the relationship as I feel that If I just let her do this I'll grow huge resentment towards her.

For all intent and purpose she's quintessential Cancer in all other respects, wants the family -and adores hers,
wants a home and kids, is a huge nurture but this selfishness just seems so out of character?? So confused. Help!

This is her chart:

Sun Cancer
Moon Gemini
Mercury Cancer
Venus Cancer
Mars Leo
Jupiter Aries
Saturn Sagittarius
Uranus Sagittarius
Neptune Capricorn
Pluto Scorpio
Lilith Cancer
Asc node Aries

She is still the typical Cancer. They like to stack money and will do it even under questionable circumstances if they have to. I couldnt deal with anyone like that even though I love Cancers, but I cant associate with people who like to do illegal shit. Its that thing called karma. If you are actually going to give her the money, then go over there with cash in hand and give it to her. Then she knows you are serious, otherwise you are coming off being manipulative with your words. Put your money where your mouth is.

i think is best for you to call it a quits these two signs are better off friends!

Moon in gemini, sounds about right to me. Sun sign is how you act and your moon sign is how you react, I think she needs to grow up and realise how stupid it would be to do that. I would never do that... thats just STUPID!!!!!!!!!!!!!!!!!!!!!

Note this: I am NOT dissing geminis, but they are free spirited and once they make up their mind thats it! (I Do love geminis though, fun to party with! lol) *wink*

UPDATE:

After, I gave her the cold shoulder and told her that in no way am I participating in any of this behaviour, she conceded and admitted that it was a stupid move and she just really felt at a loss as to what to do.

I mentioned that we are a couple and that couples make decisions together and that whatever I could do to help her out that I would. She felt that with the stress of everything that I wasn't being supportive and realized after some "shell" time that I was being supportive and that she was being self-absorbed and irrational.

Apology accepted and we can move on. I guess it's true what they say about cancers needing some space from time to time to think things out. Glad she did and that she has her head screwed on right again.

Thank you to everyone for your insight and input.
