Breaking Fast

Asalamualaikum When I was between 14 and 16 years of age. I had work to go work as part of school program for work experience. One day when I left work and I walked into a shop and bought snacks or one snack and eat them even though I was fasting in month of Ramadan. Straight away I regretted doing this. I have only once broken my fast on purpose and I’m currently 30 years of age. I would like to tell you a bit about my background. In my family home was listening to Music, watching movies, people would swear and insult and my Islamic educations wasn’t the best and until a few years ago I didn’t know much about Islam and began learning. I wasn’t shown Islam in correct way I remember being very little and being hit and I was crying a lot. I only talked to the person who was talking to me as I felt rude for not talking back to him and my teacher hit me. What I’m tying to say is my family home and madrassa experience wasn’t the best So because I broke my fast on purpose once in my life. What do I have to do now? I already repented and kept one fast to make up for the one I broke on purpose. But I made up for that fast recently, when I was about 29 of age. But I broke my fast when I was between 14 and 16 years of age. Also I didn’t know putting oil or medication drops in your ear breaks your fast. I cant remember if it was oil or medicine drops for ears that I put in my ears but it was for a medical condition. I did this a few times, I either put oil or medicine drops inside my ear whilst fasting. What do I have to do now? I have already made up for the fasts that I broke unknowingly by putting medicine ear drops oil into my ear but it was maybe after one year had passed then I made up for those fasts. I made up for those fasts by keeping one fast for every fast I broke in Ramadhan. Also I knew having intercourse with your wife breaks your fast. But I didn’t know masturbating and ejaculating breaks your fast. I knew it was a sin but I didn’t know it breaks your fast. I did this a few times in one Ramadhan when I was living in ignorance times. What do I have to do now? I have already made up for the fasts that I broke unknowingly by masturbating and ejaculating but it was maybe after three years had passed then I made up for those fasts that I broke unknowingly by masturbating and ejaculating. I made up for those fasts by keeping one fast for every fast I broke in Ramadhan. Also when I had masturbated during those time when I was living in ignorance I also was rude to someone and hurt their feelings does hurting peoples feelings break your fast . And also I was talking to a girl for the purpose of marriage but our conversation became haram in Ramadhan whilst I was fasting. I know this are complicated questions but I feel embarrassed asking my local scholar and would rather ask online please reply thank you I consider me becoming a practicing person a big blessing from my Lord, considering the environment I was brought up in, the type of family I had and with little knowledge on the deen until recently when I began learning abut the deen and even now my knowledge on deen is little. Thank you.
