Can I get her back?

So almost a month ago, my girlfriend of 5 years broke up with me. We had been struggling for about the last month, she was unsure if she wanted to actually leave or not until she finally did. She broke up with me for her own good, she said that she was unhappy and I caused that. There was things I did repeatedly that she didn’t like and I always tried to genuinely change, everything about me I tried to form into what she liked about me. We were always arguing and always fighting. Never cheated on each other, I’m her first boyfriend, and we’ve done almost everything together. First time out of the country was with her, countless vacations with her and my family. Took her out all the time. About a month before we broke up I spent a lot of money on her birthday trip just to make it special for her. One of the things she told me was that she’s at the point of the relationship that “the bad outweighs the good.” Shattered my heart, because that’s when I knew no matter what I did to make her happy, show love, show affection, it didn’t matter. Because the second I did something that bothers her she would just shut down. She’s avoidant and I’m anxious so our arguments never ever went well, that’s almost the main reason why we’re split. But god would I be lying if I miss her. Every single day I can’t stop thinking about her, checking her socials. It’s eating my soul to talk to her. She took me off all her socials almost day 1, last night she finally took the little things off like me in her highlights, stuff like that. We haven’t texted or anything at all in a month, we still follow each other on everything, I’m not even sure if she’s told her parents yet idk, I’m confused. Idk what to do, I want her back so bad, but ik I can’t text her… but it’s like would that really hurt that bad, I told her I was done chasing and I am but fuck man like this literally is the love of my life. I want her back so bad, I can’t stand seeing her without me, I can’t do it anymore and I think it would be a very long time before I get over it. I guess my question is, should I reach out. 1 text. I just want to know how she’s doing… if she’s maybe willing to give it 1 more try. I miss her so god damn much. I can’t stop thinking about her at all. We had so many plans together. My life feels so weird without her. My days feel empty. There’s something missing and it’s a piece of me. Please what should I do? Should I text her? Write here a letter? Go by her house? Drop off some flowers? Like idk, I just want her back.
