Life, Back on Track
As of this writing, there have been no news of Barbara leaving the psychiatric facility. Paul has not been in touch with her, which is quite understandable as he would never be able to trust his ex-girlfriend ever again. Paul has finally come to terms with what Barbara did to him.
What comes across from the whole traumatic episode is that Paul is a good man. He wished Barbara well when he came to know that her family had admitted her into a hospital. He returned all the donations, as an honest man would do, and only wishes to get on with his life and hopefully find a good partner one day.
