Excuse my english because its not my first langue. So, this is all started when went to this music event to see our friends perform. She had a guy friend before i even got to know her he is the nicest person on earth and i have known him before i met her we were just friend we see each other in school and say hey that's all. When me and her were just talking he came to me one day and told me if i ever get annoyed with the way they interact with each other i just need to come and talk to him and he will understand at the time i thought i was cool with it but when we became a couple i started  to get annoyed a bit because she literally get excited when she sees him like a little kid seeing his father and she always ran to hug him. She never gets excited to sees me like that i she never talked to me with that passion and that look in her eyes when she talked to him. Anyways in this music event she did all that and i got jealous and frustrated i think she noticed that and started to ask me what is wrong at the time i said there is nothing wrong to don't ruin the event for her and her friends with us. When we got home i told her what is wrong, and she assured me that i was right and she said its good that we talked about this and i talked to her guy friend too he also said that i was right .at the time i thought this is over but clearly its not. The next day at school she said hey and completely ignored me like i wasn't there the hole day. When we were going home i told what is wrong, she said nothing, but her face and tone showed otherwise i insisted about there is something wrong and she snaped at me and started screaming at me in public that there is nothing wrong and to leave her alone and she went home with her friends and left me behind. In evening she sent me a massage that we need to take a break and she need to settle down and think i told her if she was thinking about me and about how i feel she will tell me what is wrong and what's wrong and we will solve the problem together as a couple the massage is obviously longer and more detailed then that. Anyways she didn't respond and the next day i didn't see her in school at all in the evening she opened insta and removed her profile pic and it was a pic with the both of us in it and she didn't respond to the massage i thought that it was odd but i gave her million excuses. The next day i was scrolling in TikTok and i saw her active reposting vids this shows clearly she had time to at least respond to my massage so i sent her another massage even if she didn't respond to my first one and told her we should breakup cuz i cant be with a person who does these things with our first argument she didn't respond to this massage as well but she changed her profile pic and started posting stories and pics like this didn't matter to her. I was devastated and angry and i didn't sleep at all that night. The next day at school she avoided me completely i didn't even try to talk to her but she kept avoiding me. Her friend reached out to me  and asked me what is wrong i told him everything he said she told him i did something wrong but he also said that she is wrong for not responding and not talking to me about what's wrong with her . This was a week ago she still didn't respond and im still angry and sad because i didnt do something bad to her and i loved her with all my heart
