Dying from thrist of love

I'm in grade 10 16years old and I met a girl on 31st of may in 2023 and we started dating snd broke up on 15th of october in 2023. After the break up she didnt block me and we were still in touch and I started smoking and drinking and stalking her from afar everyday and crying and rotting in my bed and I get my *** together and started going to gym and locked in but still has that black hole in my chest, and the valentines day comes and I asked her to go out and its us meeting again after 4months and we had a good time and I said I missed her before she goes back and she hugged me long was like 10mins and fixed my hair told me to go home carefully thats the time I got hope again.My instinct tells me to hold onto this girl she is your soulmate she will be back oneday and I cleared out my friends and my following list no females except my mother and her I always stayed loyal for her and we hung out a few times and there was a football tournament and she was watching and thought my friend was fine and he flirted with her even though he sees how my life is tearing down after I found out I blocked the guy and deleted him from my life and asked how could they do this to me and she apologized to me. And few weeks after we started hangout more and today we went out on a dinner and I took a nap on her lap when I woke up her pants was a little wet cause I cried in my sleep and she comforted me running her hand through ym hair and gently hugged me. She says that I am the smartest guy she met and maybe I would be her husband one day and she always checked up on me after the break up my mental health and always told me that I deserve to be loved. I am thinking about asking her to be my girlfriend again. But it has low chance to be succesful my friends tells me to move on everytime but I just cant I know that she is my soulmate. When I look at her I just want to kiss her, hug her, and bawl my eyes out and tell her how much I live her and beg her to be my girlfriend again. If I did it she would probably freak out and it will be the end of me. Can someone help me? She wants a golden retriever energy and im a mix of both but black and dark on the outside
