<human>: Summarize the given text in a few sentences.

We broke up 4 days ago I don't think we should get back together (he initiated the break up but it was mutual) however, I have been considering my actions and I just genuinely feel that I need to apologize about some of the arguments we had recently and the things I said.  

I have written a nice email telling him briefly the specific things I am sorry about and wishing him well.  He was worried that I would regret the time we were together and I want to just let him know I don't regret it but this was for the best.

Are these kind of emails ever a good idea?  I think it's pretty clearly not a "lets get back together" email but rather an "I respect you as a person and I want you to know I was wrong about these things".   The arguments were uncharacteristically emotional for us and I just feel terrible that it wasn't clarified that I was being unreasonable.
<bot>: We had a nice but sad and respectful breakup and I really want to clear up a few things that I said which were hurtful in one of our last arguments.
