I don't know why but, I'm thinking of my wife's best friend in the past breaking my heart.
It's a little odd to have these thoughts, how many kids do you have with your wife?
None of your fucking business. Just kidding, I only have one child, thank you very much.
You have children, and so that means to most people that you should think about your wife and not focus on her best friend who once broke your heart. You love your wife, don't you?
I get it, but it's not like I want my family to split apart. I don't want to marry her anymore.
If you want to get a divorce from your wife, then you should have a one-on-one conversation with her and let her know about this.
