As far as my personal advice, I think you should move on and find someone else to share your life with. If what she is saying is true and she decides to make him pay child support, this girl will be a part of his life for the next 18 years and a percentage of the income that the both of you bring in (if you are living together) will always go to her every month - unless he gets custody.
Look into the future, evaluate how you feel and go from there. But yeah, too much drama, if you ask me.
