Sensitive Personal Information Violated and Shared with Friends and Family

[OTM]

My question involves defamation in the state of: New Jersey
My ex-boyfriend hacked into my online accounts( email, social networking sites) and then changed the passwords. One of these accounts contained sensitive,a mature content. He then sent emails and text messages to our friends and family giving them the username and password to this account and urged them to log on to my site. He printed the emails and gave them to the friends and family who refused to log on. Along with these printed emails he defamed my character. His intent was to shame and isolate me from my support network and cause me emotional distress. Do I have any legal recourse? If so where do I start?
Many thanks.
