To give you a more meaningful answer, it would help to know...
Are you doing it, or is she doing it?
Why is it happening?
(break up, divorce, dispute over money?)
Is everyone involved an adult?
Are you mainly concerned about the content of the messages,
or about your number becoming known to people you may not have chosen
to share it with?
Note that there's nothing especially private about your mobile number.
There are however offences which a person can commit using a phone system
(the law call it a "carriage service") to harrass (which is more than to not merely embarrass) others.
Thank you for your quick reply.
