Can anyone help me about getting back with my girlfriend?

My girlfriend broke up with me several days ago. Our mutual friend didn't liked the answer ,, No, Never.’’when she asked her about if she gave million dollars to us to make a big wedding if she would marry me, so she talked about with her that it was not right to say that and treat me like that especially in front of other people. My girlfriend came to me crying and said that we were completely different persons and we broke up on good terms. After breaking up we contacted each other and she said that we were emotionally depended on each other and that was not good for us. Couple of days later she said that because i was too commited , it made relationship toxic and she lost her identity and personality. She said that she wanted months before she contacted me again only to be friends but the friendship she proposed was more like just contact with each other once in a while. I answered that friendship was not possible when i loved someone. when we were relationship i was talking about marriage, was jealous of other guys, did not liked revealing clothing on her and etc. she said that she just wanted to have love with happy moments and ,, living in moment” commitment with 0 preasure of too much serious relationship. Now i realized that she was right cuz im 16 and she's 18. I spoke to her and said that i was ready to start from 0 and be the perfect boyfriend to her but she said no because she doesnot belive me anymore. In 6 days there is birthday where we are both invited and she will be coming. I want unbeatable advice about getting her back with me. i know that you are imaging that it is a teen love but i truly know that love from me is serious than anything. Please let me know about what can i do. thank you 🙏
