Thank you for your question - can you explain what exactly you have sent on FB and and when was this?
My name is ***** ***** I have been a solicitor for more than 35 years.
Nothing you have posted on facebook will have any impact on the financial settlement at all - the family court will not deem it as relevant if he tries to bring it up.
However you should not make any other attempt to contact her in any way as if you did she would be able to ask the Police to deal with it as Criminal Harassment
I hope that this is of assistance - please ask if you need further details
