Totally hear you on that, Kev. Maybe I’m not getting it, but if your GF knew that what she was signing was fraudulent, then she is every bit the scammer that her mother is, and I would stay far away from her. If, OTOH, she didn’t know that it was fraud (and didn’t even have an inkling about it), then I would question her money/business savvy, and would be very cautious about getting involved with someone who could “inadvertently” get you both in trouble down the road because she “didn’t know” what she was doing.
I know this is probably not what you want to hear because you’re obviously attached to this girl, and that’s why you keep questioning the relationship here, but you have to use common sense when choosing a spouse. Statistics show that money is one of the top issues that can cause marital strife and divorce. Choose your spouse wisely.
Also, I’m a firm believer in knowing when something is definitely right. If you’re questioning the relationship this much, it’s probably not the right relationship for you. Again, just my 2 cents.
