I am sorry you are suffering but this girl sound awful and horrid. The only kind of communication you should have with her is saying thank you for leaving you alone. Forget about money loss, you can eventually get on your feet. You should be happy dodging the bullet. Imagine you married this horrid person and had kids. She’d abuse your kids too. Move on. Stop looking for ways to talk to her. Rejoice having life without this manipulator and user.

I also recommend you seek therapy to get to the bottom of why you’d settle for such person. You need to process what happened so you’ll never date such people.

Good luck and hugs
