I have seen what you speak of first hand and then some. That's why I would never marry one. And a few did want to marry me (and probably still do), but it will never happen. And I tell them that. I am not saying it is impossible to find true happiness with one (as some on these boards have), but you'd better have ESP, eyes in back of your head, a strong heart and flawless judgement.
I don't think it's possible with a FS amp girl. Just as an illustrative example---(I could choose many) I was with one particular Chinese girl, we were almost a year into the off site relationship. Always telling me how much she loves and adores me and how she never met anyone as special as me in her life. About as tight as 2 people can be considering the odd nature of being with a FS girl.
Then, one Sunday as I am driving to pick her up from work, just texting a little about nothing in general she sends me a text saying "I will give you the information tomorrow".
Obviously not meant for me. When I asked what she meant she said "I was joking", nonsensical ---but I dropped it.
Then the next day as we are texting back and forth she sends me messages intended for me and some mixed that were obviously NOT intended for me.
Messages such as "room number? Floor number?" and later that day "so nice to be with you today".
Of course she lied saying "my friend borrowed my phone to make plans with her boyfriend because her phone had a dead battery" and that those messages were not hers.
Even if I was stupid enough to believe that it wouldn't explain the prior day's message "I will give you the information tomorrow".
This from a girl who swears allegiance to me 'until our end days' and that she doesn't even have a customer's number in her phone. Still don't know if it was transactional, for fun, or if it happened again. Doesn't matter. Trust was broken and that's that.
I am sure I am not the only one who can relate horror stories of dating FS girls who on the surface seem to be as sincere as one could be. When in reality they are anything but sincere.
uniquelyme estimates 1 to 3% of these girls can be trusted, but I think that's being awful generous.
