Messaging wife after filing for divorce

Hi, I was married a year back and we were pretty happy for the first one month. But we had a fight and my wife felt we are not compatible. It was also my mistake that I hardly used to call her during day. After the fight one day she told me about the emotions she still had for her ex boy friend who she was not allowed to marriage and was irritated on me for days. Again my mistake that I told about this at home because of which got more angry and left home. I later discovered that she even met that guy after leaving home. From last one year I kept messaging and expressing my love. Initially she used to respond rudely but later she stopped replying completely. We have filed for mutual divorce last month and our divorce is scheduled for July 2017. I am still in love with her and can't stop trusting her. Last month on valentines day I tried calling and later messaged her and she called me back saying that now we have filed for divorce and if I message her again she will file a police complaint. But still at times I have a deep urge to message her. I am still very much in love with her and consider deeply that she is my wife. Will it cause a problem even if I message her once a month?
