There's this girl, she and I are semi-friends. She's new this year. We work together and I share my locker with her at school cause it's hard to open hers. She told me that she has a boyfriend. She also told me she thinks MY boyfriend is cute. She's really flirty with him and it scares me. I told him it scared me yet he still accepted her snap friend request. She said it was so he and I could talk during work(since I don't currently have a phone) yet she spent the whole time snapping him. His responses seemed somewhat flirty and she tried hard to look good for the pics she sent back. She has a boyfriend. My boyfriend told me, I have nothing to worry about but after that, I'm not sure. she and I are friends, she's kinda cool. I'm just really scared. What do I do?
If you make a fuss about it, you will drive both your boyfriend and your friend away.
As 1ozzy has said, you must suffer in silence.
Leave things alone and pretend that you don't notice.
What will be, will be and you can't change anything by creating a fuss.
This happened to me once at work though not at school, and the only thing I can suggest to you is to talk to your boyfriend about it, and hopefully he will reassure you you have nothing to worry about.
