How to get your ex back? ⇐ Pick Up

[Guest]

Hi all! I never thought that I would decide to write about this, but an outside perspective and advice could help me. In general, I am a modest guy who does not know much what and how.
I met a girl for about 3 months, she and I were 18. She was an old classmate, quite timid, but a good girl, on a scale of appearance 7/10, but she sunk into the soul. She studied with me from 5th to 8th grade. Even at school I liked her, but I didn’t put myself in front of her.
When I entered the university, I accidentally met her in the library, then found her on VK and wrote. We talked a little about the topic of how the school ended, and that's all. I helped a little with my studies with tests, although we have different directions. Where in April-May she began to write more often and invited to a party, there we did not interact with each other, in general, at first each sat with his company, towards the end we only talked. But the company and I left early. As a result, she herself wrote to me that evening that she had come home and that everything was fine with her, I was like that - ok. After she called me to the cinema and off we went. We walked, hugged, then she called me home, where we kissed for the first time, after that there were again walks and preparation for the session. Then she invited me home again, here I already screwed up a lot, a PA could happen, but the condoms turned out to be far away, and even not the same. BUT we still continued to spend time together, I often visited her at work and gave goodies. Then she had to go to her relatives, and at that time I successfully got a good job. We agreed that we would celebrate her birthday upon her arrival, and I would just take a day off on the right day. But then something went wrong. At first, she didn’t really celebrate her friend with her parents because she arrived only that day, and the next day we had to celebrate everything with her and, perhaps, finally retire. BUT she got sick, I decided to arrange a meeting with her when she gets better (I was still working on shifts at that moment).
As a result, she completely lost time and something worried her, then some problems arose that she did not want to share about, saying that you are a good guy, you don’t want to load problems. Then I realized that something had happened, I began to ask if everything was in order, in the end I decided to roll out a message to her, in which I wrote that I wanted clarity and I did not want to endure reticence on her part. To which I received an answer - I don’t see any problems, let’s remain friends, I wrote in response to this, it means you want to end it all like that, sad and insulting, I wrote that I love her, in response - you don’t know me enough to love, despite the fact that she was the first to write about love, about what she was afraid of losing, and she told me this live. As a result, I tried to clarify all her words, based on her own arguments, offered to meet and talk for the last time - to which she replied that she didn’t want to and that she was tired of everything, the day before that I gave her a gift that she had prepared in advance on the DR, left near the door, because he knew that he would not want to talk to me (he offered to talk a bunch of times), she said that she did not deserve a gift, BUT she herself asked until 5 days before the DR to tell me what I would give. Then I decided that everything, the end - I added it everywhere in an emergency, then I unlocked it and started writing, in general I went crazy. I started calling - to which I received a response - why are you calling a third time, explained that I was doing garbage - I forgave, then I stopped recognizing myself, started writing and deleting messages, the content of which explained my actions and deeds, today I decided to give her a gift , bought flowers, a cake, came to her, she doesn’t open the door, although she’s sitting in VK and it was heard that they approached the door, she doesn’t react at all, she stood, thought, left gifts and went, apparently she got it at the end, and maybe even scared.
I don't know what to do, because this is my first relationship.
