I am f17 and i have been feeling conflicted with my friends. (f17 and f18) I will call them person 1 and person 2. (2 is the older one)

So we met 1 year ago in school. We became friends pretty quickly and got super close. Then we bonded because a person in our friendgroup was being very distasteful and making everything suffocating.

But my problem is with person 2. She and her are both people with strong personalities. But i back down pretty quickly and just comply so conflict doesn't become bigger then it is. But she always makes it a huge problem and somehow makes it about me? Like she is never wrong?

Me person 1 and 2 were in a groupchat, we would send funny stickers of each others face. So when me and person 1 did this. 2 got mad and we didn't realise. (When she messages you can't see what she is thinking. She texts pretty dry so i never know if she is mad or sarcastic) Anyways she said "stop" and i thought it was a joke and continued. Then she left the groupchat and thats when we realized she was mad.

We texted her privately to say sorry about what happened and we didn't know she was mad. She kept saying "How did you not know? Sorry but if you didn't know when i said stop i think that is pretty stupid." I told her the exact reasons. That her texting is pretty confusing. But i still apologized told her that next time i will try to read the messages better. But she went on and on how she did not understand and that i must be stupid. This was the first time i got a red flag out of her.

She also gets mad about the most random stuff. Where i even got scared to ask her stuff because i would not know her reaction to it. A different friend outside of this said this was pretty sad to see me being scared to ask anything to her.

But after these kind of conflicts after a couple of days of us being mad at each other and ignoring each other she goes back to acting like nothing happened. And that stresses me out. I like to talk about conflict and make sure we don't have any misunderstanding anymore but she brushes it under the rug and acts like nothing happened??

After this many other discussions happened like this where i apologized a thousand times and she went on and on how i am stupid and that me apologizing does nothing and that it is all my fault. And when i tell her she is being hypocritical she turns it back to me again??

And last month she did this again and i was done. It was a discussion about something somebody else did and when i called it out that she does that too (which she always says about me. She always makes my mistakes open to the public and likes to point out what i do wrong) she got mad at me and said "Oh so it's all my fault?" So i decided to not talk to her for a while. But now she is texting me to hang out and acting like it is normal again?
