This incident happened a while ago and it keeps bothering me so I need some outside opinions.
While on a trip with my friends, me and one of the friends had a falling out of sorts. We used to be very close (best friends) as kids and then she moved countries when we were 15, we managed to keep up on and off and then life got in the way. We finally reconnected over email during the pandemic and then decided to take a trip a year later with 2 other friends. The trip was a bit rocky for me and this friend. I think there was alot of pressure that each put on this trip in terms of reconnecting and trying to reconcile with the fact that so much had changed between us even if we were able to interact without any awkwardness. Finally, we had a heart to heart towards the end of the trip and she said things along the lines of not caring to further our interactions after the trip, her having made great friends since she moved way etc. I was caught off guard a bit, but it’s understandable, I just didn’t think it needed to be as abruptly put. The next day, we continued to interact as normal, and then in the evening we were on the subway and my mom got online on WhatsApp. My mom and I had been playing phone tag for a few days because of the time difference. My mom and I started texting and she asked how the trip was going and I told her what had happened the night before and I started to vent a bit. I should mention my mom and I are very close and I consider her to be my confidant. Later on that evening, this friend confronts me saying she saw the things I was texting my mom about her. She was next to me on the subway and she saw her name in my texts so she started reading the conversation between my mom and me. She didn’t seem inherently upset but she was mainly confused why I was even texting my mom about what we had discussed since our “heart to heart” took place the night before, and she thought I had moved on already. I was very upset and hurt that she even read my messages but she said that it was natural since my arms were extended to my lap while I was texting and since she has 20/20 vision, she could very clearly see everything on my screen. She said that I should have done a better job to hide my screen if I didn’t want her to read my messages, and that it almost seemed as if I wanted her to read them since I was texting about her while she was next to me. I was so dumbfounded. For one, I did not ever think she would read my messages, I never meant for her to read my messages. I don’t know how much of the text chain she read between my mom and me and I am feeling a bit bad about of some of the things I said in those texts to my mom about her, given that she might have read them. But I also feel like she shouldn’t have read my messages even if she saw her name and was curious. After that, I spent the rest of the trip (3 days) on my own and didnt bother talking to her.
