Wedding invitation. An insult to me?

What's with the invitation letter? Is it an insult or what? Why would I wake up to a wedding invitation letter from my lawyer friend? The very lawyer who helped me with the divorce I was against 😡
This lawyer advised me that it's not worth holding on to a sinking marriage, she called my wife a red flag but now what am I seeing? That he's marrying the very woman I divorced just after 1 month of divorce! This is unheard of?

I want to take to them a special gift, a book written of everything I've been through with her, of every joy and lows we've been through and thank them at the end for a perfect betrayal...no, am going to stop that wedding 🚶
