One of my close friends thinks I was talking behind her back but I wasn't. She is also upset cause of something she THOUGHT i'd do but i didn’t do it. Now she won't talk to me

Maybe for now the best thing to do is give her a bit of space and let her know that whenever she feels ready, you’d really like to talk things through and have an honest conversation about what’s been going on. It could also help to sit with some other people in class for a little while, just so she has the space she seems to need right now. 

I totally understand that being ignored by someone you care about can be really hurtful. At the same time, if she believes that you've been gossiping about her, she might be feeling upset or unsure about whether she can trust you at the moment. If you genuinely know in your heart that you haven't done anything wrong and you've acted with good intentions, that's important to hold onto. 

It's natural to want to fix things straight away, especially when you care about the friendship, but sometimes the kindest thing you can do is give it some time. Space can be really helpful for both of you to process your feelings, and it gives things a chance to settle before having a conversation. Just be patient with yourself and with her — whatever happens, you've done what you can by being respectful and giving her the time she needs. 💛
