What a caring, loving aunty you are!
Unfortunately, this young woman is way too troubled for you to fix. I think also that she needs some sort of residential treatment and, for your own safety (you don't want dangerous people coming to your house) it is best not to have her live with you in the long run. Hate to be skeptical, but if she was raped twice...would she want to go on an internet dating service? Not saying she wasn't...would never say that...but in my opinion it's odd. Also, the STD could have been from any time if she is sexually active and careless. She needs to learn to love and respect herself more and make safer choices!
Hugs and good luck!
