The "obsession" was a very long time ago. I first met them in 2007. We started having disagreements a couple years afterwards, then decided to part ways for good in 2014 after many attempts to try and reach a peaceful resolution without getting authorities involved. Between 07 and 14, this was nearly a yearly thing. No real attempt to obtain a restraining order was made during this time, that I know of.
Since then I did not voluntarily choose to contact them because I knew it was "over" and I felt there was nothing else I could do to fix it. What I did instead, was vent to friends online about my failure with that friendship, telling them the whole story. Then what would happen is that there would be a fallout, and said former friends would go out of their way to impersonate me and harass that individual, which painted a target on my back because they were able to have knowledge of certain events that would trigger red flags. This happened thrice, in 15, 18 and finally, 21. The first two instances in 15 and 18 were both instigated by the same individual who I cut out of my life.
