A chick travels all the way from the UK to stare at me with wide eyes. Why would she do this?

A woman I was acquainted with. I left on bad terms/for the greater good. She’s been sending people to harass me and whatnot. They’ll do shit like stare at me with super wide eyes. Basically stupid shit to bait me into reacting. And it’s been happening for years. I would text her afterwards asking her why she is doing this but I would get no reply. Tbh I’m like 64% sure it is her. But what I want to know is why she is doing this. I texted her like “why are you staring at me with wide eyes and not saying anything” this happened in PA L. I fly to Oshkosh Wisconsin, go into a Walmart and I see a dude (with a woman) staring at me with wide eyes like he was overdoing it through being super expressive. And the chick with him was looking down and laughing. Is that her new dude or something. And should I fight him for taunting me. I don't know guys I love her and she betrayed me. Why does is she cold turkey over text and going out of her way to taunt me in person. I love her and want the best for her but not at the expense of myself
