Well, when would you tell a girl that your dad beat you? Or that you and your ex had an abortion? Or any other very, very personal and traumatic experiences? These things are not subjects you just throw out there on dates. Dates should be playful and fun and about enjoying each other, not getting into heavy psychological trauma. That's not normal or healthy behavior. It's oversharing of a specific type and it's usually done by people who have a lot of issues, one of which is maintaining a victim identity, and also being HIGH DRAMA. They tend to be negative and look for the worst in everything and complain a lot. You WILL end up the target of her complaints.
