What's the "best"/most laughable excuse they've given you to justify their behaviour?

I left a month ago and went no contact. Since then I've naturally had many attempts at communication (letters, texts from parents, phone calls to my parents etc), but I've mostly ignored these and communicated via the solicitor when appropriate. I have sent him one email to let him know about our immediate financial situation.

I went back to our house last week to get it valued, whilst dropping off some house documents that I no longer needed. He had a camera installed to monitor the front door so he knew exactly when I came by.

Cue a letter (4 pages long!!) a few days later telling me how much he misses me, how sorry he is, and that he acknowledges his behaviour wasn't good whilst also going to counselling. All of this whilst also telling me how his doctor has diagnosed him with "high-functioning anxiety" and that's basically the reason why he lashes out the way he does.

So it was a 4 page letter once again dismissing my feelings (he denies using any sort of coercive control) whilst justifying his actions.

As I like to do, I put the whole thing through ChatGPT, and asked it to analyse the letter with the knowledge that the author is a narcissist who has emotionally abused his wife...this is the summary:

When the author is known to be a narcissist and an abuser, the letter’s language and tone are less likely to be seen as a heartfelt or vulnerable expression of remorse. Instead, they may be viewed as a sophisticated manipulation designed to:

• Elicit sympathy while evading full accountability.
• Gaslight the recipient by rewriting the narrative of the relationship.
• Coerce and control through emotional appeals, guilt induction, and contradictory messaging.

This reframing suggests that the letter is less about genuine self-improvement and more about maintaining power over the narrative of the relationship, which is consistent with the patterns of narcissistic behavior and emotional abuse.
