What happened to me??

I'm new here, and I want to start by saying... what an amazing site !!!

Without going into a lot of details about my story, prior to a little over a year ago, I had never even heard the term Narcissist, yet alone known one. Come to find out, I think I married one. Tons of reading, in therapy for a year and a half I made the break three months ago by filing for a restraining order against my husband and have since filed for a divorce.
He, unfortunately is representing himself in the divorce (only a 2 year marriage) and he is asking for items that are my personal things prior to the marriage, and thousands in cash for stress he said I caused him... His letters to my attorney are letters directed towards me in hurtful ways that have nothing to do with the divorce. With the divorce just starting I fear the long battle I have ahead, not only with me having to pay attorneys fees every time my attorney has to answer one of his silly request, but he will stretch it out as long as he can as a hold over me.
Yes, NC... After the first few text to my children (from a prior marriage) I changed their numbers. but he continues to text my friends, business partner and other family members. None of the text are ugly, he is not saying to tell me anything so its not third party, more of a "hey I'm not gone" kinda thing. He has also sent cards to me in the mail that were unsigned, with no return address, but clearly his handwriting.... I feel it's still a total disregard to the court ordered restraining order??
I guess you could say I'm in step one of the healing process "understand it" I'm clearly having a real hard time with this first step so any advise is greatly appreciated. Thanks for reading :)
