Dear relatives/friends of my parents.

Please stop asking why I broke up with my ex/when I'm getting married/when I am having babies.

It is none of your concern and I want you to stop harrassing my parents (who in turn harrass me) about these things.

No you are not being caring and considerate and as how you may perceive yourselves to be, I do not want to answer your questions and you are coming across as being nosy and insensitive.
