Could this cause feelings of betrayal?

A form of ual harment? Because there's evidence that I affected another girls emotional wellbeing because of it. She's like emotionally attached to me. She was depressed and suicidal at school and I did it to raise her low self esteem now she has a jealous issue of who I'm dating it's written all over my gfs website. She prob didnt know I existed before this. It was a gesture but according to facts it is still ual harment and since I traced back her dads ip address to 'i have a huge *****' I'm worried
