Dear [Name],
I am writing to apologize for my tightfistedness. It is not something I am proud of, and I am sorry for the hurt it has caused you.
I know that I have not been generous with my money, and I understand how this has made you feel. I know that it has put a strain on our relationship, and I am sorry for that.
I want to explain why I have been so tightfisted. I grew up in a family where money was scarce, and I was taught to be careful with it. I have carried this lesson with me throughout my life, and it has made it difficult for me to be generous with my money.
I understand that this is not an excuse for my behavior, and I am sorry for the pain it has caused you. I am committed to changing my behavior, and I am working to become more generous with my money.
I also want to apologize for not being more open with you about my financial situation. I know that I should have been more honest with you about my finances, and I am sorry for not doing so.
I am committed to changing my behavior and becoming more generous with my money. I know that it will take time, but I am committed to making it happen.
Again, I am sorry for my actions. I am committed to changing my behavior and becoming more generous with my money.
Sincerely,
[Your Name]
