I'm so sorry to hear that you're feeling anxious about your ex likely contacting you. It sounds like you want nothing to do with her, is that right? How has she sought to contact you in the past? Is there any way you can unilaterally block her via those routes? Would that be the best thing for your healing?
Posted this in a previous thread but might as well post it here as well.
July 2nd, 2011 - We begin talking out of the blue. Couple weeks later I get these huge messages from her confessing her love for me. By the end of summer she's sending me huge messages explaining that she's a lesbian and that I was forcing her to go against her sexuality.
July 6th, 2012 - She calls me crying in the middle of the night begging to get back together. We get back together. By the end of the summer she is again a lesbian, denies that we ever had a relationship, and claims that I'm stalking her.
July 11th, 2013 - She calls my mom at 5am asking where I lived and what I was doing for work. I got in contact with her through my own means, and for a few weeks in August 2013 my life was chaos. She hit me in some random parking lot when we tried to talk things over, then spent two weeks obsessively texting me until the wee hours of the morning telling me to kill myself. When she got bored of fighting with just me, she began texting my friends. Then claimed I was stalking her.
July 1st, 2014 - Tried to instigate a fight with me on social media, then began texting one of my friends. Again, this lasted until the end of August. I got tired of her garbage and took things to court at the end of September, with another date in December. Seemed to have pooped herself out by the first one and didn't show up to the one in December because she was "scared" of me according to her dad.
April 29th, 2015 - She violated the court order and the police went and had a talk with her + her dad.
Blocked her
three Facebook accounts. Blocked her
three Twitter accounts. Blocked her on Instagram. Blocked both of her younger sister's Facebook accounts (at one point she was creeping on me). Blocked her Dad on Facebook.
I don't want anything to do with her, but if something does happen and she pops up again (which is 99% likely), I'm afraid I'll crumble and agree to something stupid like going to counseling with her.
My adopted cousin suffers from Fetal Alcohol Syndrome and the toll her behavior takes on my Uncle and Aunt has almost destroyed their marriage. It would be a Godsend if one of the people my cousin has wronged threw my Uncle & Aunt a bone and tried to help in some way instead of making my cousin's problems worse by being vindictive and vengeful towards her.
Every time I've reported my ex to the police or done something to make it clear that her behavior isn't acceptable (IE court), I've broke down crying in private afterwards. I know how much my Uncle & Aunt are affected anytime my cousin gets into serious trouble, and I feel really bad putting another family through the same thing, even if it's the right thing to do.
