Handling aftermath of living with a bipolar girl

TLDR: Crazy ex girlfriend
Ughh I lived with my ex for 6 months dealing with all the issues she had both with entitlement and her manic episodes. Pretty wealthy father so she learned from
Her Chinese mother how to act. She decided to call the cops on me while I was asleep and then I had to keep being chauffeured by the cops to protect me during her manic nonsense. Changing medication was a mistake. We wanted to have children together, I wanted for us to get married since I’m hitting that age (M25) (F28). Torture mentally after this hell of a breakup. Any advice on how to make it less bad would help. Don’t tell my wallet lol.
