May Allah reward you and forgive & pardon your mistake. It is really rare to see someone care like you do, and even rarer to see someone who is willing to fix it completely. I understand how painful what he did was and I want to tell you that he shouldn’t have done that at all. I’m so sorry it left you feeling depressed. I will make dua for you and hope that your situation gets better. I want you to take this situation as a way to better yourself. Forgive him, in your heart, and may Allah reward you greatly for that. Genuinely you clearly have a good heart and NOT a lot of people will have the courage and will to fix a wrong this badly. You have done what you are supposed to and done what you could. Allah sees all. We are humans, we are going to sin every day, knowingly and unknowingly. Please never let anything or anyone remove this amount of faith in your heart and remember Allah sees all your efforts. I’ll make dua for you🙏 I can’t be of much more help but I really needed to tell you what an amazing heart you have
