Holy crap!!! That sounds like a nightmare!! I understand your shock and heartbreak. Sounds like you could process that for a year and still be dumbfounded. Clearly she has some serious troubling issues. It is interesting that she told you and didn't lie. Maybe you were a surprise to her and she didn't expect to find love, like she was caught up in something that is destructive to her soul and then you came along and she doesn't know how to get out of the lifestyle she is in.......there is more to this sad girl than you know, but she is lovable, though you may need to step back and see what is best for you
