Am I doing good in life?

I am a introvert person but I wanted to ask how to be better and if I am doing fine? I got 9 cgpa in 10th but in 12 I only got 79.8% even though I was above average and could easily get 85+ but in Jan 2015 I met a girl 3 months before my exams and my focus changed to her from study. I did my b.tech in 2019 but I never went to college, didn’t gave internal exams and assignments. I was only onto final exams but thank god I passed on edge but never got back, during this period that girl I met in 2015 was still with me, I was only focused on her and due to this I was never interested in making new friends even in college, I was always alone and with her. Because I focused on her again in college and not on studies or gaining any skill , due to short attendance and less marks I was not eligible for campus placements. I gave tonn on interview but they laughed(interviewer) at me for not even knowing basic coding. Somehow from a reference I got a job in 2020 after a year of completing my b.tech, my focus was still on that girl and we dated for 8 years. After I get the job then I started to focus on my carrier but the initial company was not good so I left in 10 months and joined another, this is a Indian service base small company. That girl was still with me but now fights became normal in relationship, shw wanted to leave but I always said sorry and tried to keep her. Also, in my second company I gave my blood and sweat to learn and grow , they have twice a year appraisal cycle and I learned alot there, I used to work and then study, I sit for live 15hrs a day in front of laptop to work and learn and here below is how proceed in my carrier 2020 1st company - 17k p.m 2021 2nd company - 4 lpa 2022 (jan) - 6lpa (as part of contract salary increment after 6months on good performance) 2022 (dec) - 8lpa (appraisal) 2023 - 11 lpa(appraisal) 2024- 12.65 lpa (appraisal + promotion to Sr. Software Engineer) 2024 switch to 3rd company - 25 lpa + 2l joining bonus

I have a total of 4 years 3 months experience. Last year I asked that girl to marry me , she said no because I shouted on her once when she cheated on me with a coaching friend(no physical relation) , I got so angry and shouted like he’ll and she gave me this logic and left, we were together last year 2023 on 25 April on my birthday and 26th April 2024 she got engaged and a week back married to someone. I came from a middle class family, all this still haunt me, I have given her everything and didn’t even focused on me , making friends , in college, study, even job but still for thay 1 shout she said no and started here life. Now here I am with no friends , no confidence, full of pain inside and demotivated. I don’t know if I am doing fine professionally and what all I have missed and how to get confidence to talk to people face to face, I don’t drink , don’t smoke so don’t even get invite for parties. How to handle this set back? How to grow professionally? Any advice? Suggestion? Guidance?
