Kiyomasa-sama
This is Kawaguchi Hidetoshi. This is a humble answer to the question.
It is really important that Kiyomasa sincerely regrets and regrets it, and as all of the respondents said.
In particular, having a sense of “shame” is important and a good act in Buddhism.
Regarding “shame,” we are also dealing with the following questions.

Now, from regret, remorse, and shame, the question is what exactly we can do next and what we should do.
Of course, along with the fact that similar mistakes will never be repeated, it is also about whether there is anything that can be done for mothers, ex-wives, and sons, for example.
If everyone were alive, one thing would be to express a sincere apology or apology, whether in person or in a letter without meeting again. Depending on the other person's reaction, there are times when they have already forgiven you, and it is possible that they don't care, and if that is the case, the suffering will be alleviated quite a bit. Of course, the opposite reaction is also possible, but that means that it becomes clear how to deal with the other party in the future in response to that request as something more specific. Of course, it may become more clear there that nothing can be done anymore.
Even if you continue to worry alone, you may continue to suffer even more in the midst of exaggerated delusions. It is necessary to aim for good deeds as realistically as possible.
I would recommend that you perform the filial piety that a mother can do, if she has already passed away, that you can perform as many memorial services and merit conversion as possible to your ex-wife, make amends with what you can do by showing apology and sincerity, and that you can give love to your son from now on, respectively.
The past that has passed will never be recovered, but if you keep getting caught up in it, it won't change at all. I think the question is what we should do now and in the future.
I would be very happy if this was an opportunity for you to think at least a little bit about what you can do.
