It’s not surprising that she didn’t tell the truth originally. It’s hard to be truthful about yourself when you are doing things you shouldn’t.
I am betting she was unable to tell the truth because she was trying to convince herself that everything was okay.
But, it never was. Sounds like she got caught up in the moment and when she was vulnerable, there were people just laying in wait.
I feel for her. I really do. People who use you for their own gain can inflict irreparable damage.
