I would like to say I have this giant mountain of a regret sitting in my past, but I don't have that luxury. I would love to regret every moment spent with my XH just so that I could then honestly hate those years and purge them from memory...

But I won't purge my two kids. I wouldn't then and I won't now.

In essence, every regret you wish you could change would probably come with a price. It makes it easier to live with when you realise you couldn't afford to pay it.
