I thought it was fairly clear that Harry's issues with his family run very deep and far precede Megan by some considerable way. Megan is I think merely a similar character who rather than trying to hold back sort or prevent has encouraged.
And that the trigger could very well have been becoming a father - the emotions that he felt then could have brought into sharp focus his own childhood and the anger that he felt.
In essence not an awful lot different. Chelsy and Cressida walked away for a reason - and I suspect we are seeing why now
Luckily Chelsy is a very clever, well educated girl who wanted no part of the shit show. She really dodged a bullet.
Exactly cant you see in this comment that the issues were already there
