If your story is actually real (hard to believe someone would let themselves be taken in the way she took you) She's trying to keep you in her life so that she can use you for your money still.
Why would you caretake someone like you did her before you were even in a real commitment. 8 months? She took you to the cleaners so get the help you need to fix your White Knight Syndrome (google it and read about yourself). If you don't fix your need to be fixing others, you will fall prey to another woman just like her ~ a User.
You need to work on your codependency and learn the difference between Caretaking and Care giving. Caretaking is unhealthy for yourself and who you caretake.
Block and delete her and don't meet a woman's children until you are in a relationship that you know is going to be successful.. and you're doing it with a woman that has her shit together. She's got issues and she's abusing her children by bring men in and out of their lives like she's doing.
Block and delete her and get her out of your system with cold turkey zero contact withdrawl.
“The willingness to accept responsibility for one’s own life is the source from which self-respect springs.” ~Joan Didion
