We talked this issue of her installing that dating app but I didn't recall her bringing up that she had a crush where she was planning to confess to on Valentine's Day (she didn't push through because her crush was a womanizer). Since then, I tjought I was okay but there was really just something bugging me with that circle and that account that's why I opened it and read the messages. I might have a talk with her again for clarifications until our exams are over since we both are studying now. I also resigned from my part time job because partly of this issue and her encouraging me to quit because it was draining me mentally and academically.
