If you explain how they hurt you and you get no message back, that silence is the answer.

 They don't care. 

You can acknowledge that fact for what it is or you can argue with it and try to give it other meanings.

 You're wrestling with truth so you don't have to make uncomfortable changes and the problem is you. People who love you care about how they make you feel. If you embrace this fact you'll shorten your suffering and set yourself free.

This is applicable to all sorts of relationship.

It was Crawford who taught young Princess Élizabeth much of what later made her fit for the throne as Qúeen Élizabeth II. 

Even though Crawford had a long-term relationship that was due for marriage and the princesses were well of age, Crawford as a nanny, wasn't allowed to marry or leave the royal family until then Princess Élizabeth had engaged Prince Phillip.  

For 17 years, Crawford literally gave her all for the röyal family, but in the end the röyal family cût her off! 

They stopped giving her pension, kicked her out of the grace-and-favor house they gave her in the Kensington Palace, and in the end when Crawford dìẹ̀d, Qüeen Élizabeth II didn't even send her a flower or mourn her. 

Crawford's offence was that after she retired, she published a book that shared her experience about all the years she served in the royal household.
