I understand you trying to avoid the routes where you might see her.I did the same recently.A person from my past tried to contact me that she was moving to my town.I didn't respond to her texts or calls because it induced anxiety in me.I don't want to rekindle the relationship. She and her entire family were toxic to me back then.So what's the point?I went shopping with my friend and lo and behold She was the sales associate there.But she pretended not to recognise me,put up a scorned face.It induced a mild anxiety in me.I decided not to go to that shop any more.I felt the need to protect myself.The mere sight of her aggravated my feelings.I don't want that to happen again. Anyhow plenty of places for shopping around here.I get it what you said.Take care of yourself.
