I mean, didn't Dad say anything to you about using his powers except in an emergency? Octavia knew her father had a life outside of her.
While she might have forgiven her father for sleeping with someone outside of her mother Especially when she found out she was cheating first , that didn't mean he liked this asshole who had helped play a role in her family's issues.
Presumably, Octavia continued to live with her husband from the time of their marriage she would have been between 12 and 15 when they married to her husband's death.
The story line is generated along the confines of the life of the doctor.
