You could learn something from narrated short stories. Even if those stories come from Reddit. Obviously, not a book story, but someone's experience with a situation.
Like what? They left you at your home alone going on a vacation without saying anything as they desired to live in your home, your father's new wife told you to clean your own home, you call them and they act like complete and total utter sh*t, but still desire to live with you? It screams bloody red flags. The lack of even saying anything about the vacation is communicating to her that they are not on speaking terms so for anyone to say it's not a big deal, you have no self awareness and STFU!
Her dad saw her as a pushover, that's why he acted like that. It's great she did what she did after the honeymoon sh*t. How dumb is her father. Highly abusive behavior even as you desire to live in HER HOME. The father got what he deserved no relationship with his sh*tty ex-wife, gf whatever she was and no relationship with his daughter.
I wouldn't have even bothered calling to ask about the honeymoon sh*t and kicked them to the curb immediately and to their faces. If you are going to engage my hospitality with your lack of hospitality and trash behavior, don't be surprised to find out your behavior is met with the same. You want me to act in a way that you don't? Act right or don't act at all. GTFO!
The daughter's mother didn't even leave the home to her father which tells you exactly what she thought of him. Good for her.
