My question involves defamation in the state of: Texas
I recently completed a divorce which was not initially ugly, but turned that way as a result of one of my ex's girlfriends. This person also insists on getting herself involved with my children, specifically my daughter. She sends them text messages scolding them when she feels they aren't treating my ex the way she thinks they should. The first time it happened, I texted her back on my daughter's phone, identified myself and told her that if she wanted to discuss issues such as these then she should deal with me directly. Her response was classically passive/aggressive: She said she would not read any further texts and would delete them. Fine.
Today, about 3 months later, it happened again. Another text to my daughter. I replied on her phone and said that she must cease and desist contacting my daughter and if she doesn't, I'll file a police report. Well, her response was to send a text message to MY cell phone saying "BTW I'm not scared of you FAT BOY"
I then filed a report with the Fort Worth Police Dept citing harrassing phone calls (this after I called the police to ask what to do). I wrote exactly what she said and that I wanted us to be left alone. My question is, does she have any legal recourse against me for filing a police report even though it is factual? I want to make clear that I never at any time insulted her, called her names or threatened her in any way. I have the text messages saved in my cell phone with her number attached to them. I did say I would contact police, but that's the extent of it.
I am seeking no damages or anything else. All I want is for us to be left alone. What is the most likely outcome of this?
