Well, I think you have thought this out very carefully and you are ready to take a break, whether the break be temporary or permanent.
I love my new lifestyle of leisure. It's been seven months now, and I can't even imagine having to go back into an office and keep a busy schedule any more. So I would definitely recommend you take a break, enjoy life, and see how it goes. If the leisure time continues to be enjoyable, you may be done with work. If you get an itch to start doing something again, I suspect many opportunities will come your way.
And yes, I still wake up every day and say to myself, how did it come to be that at age 46 I don't have to work any more? Seeing all the news reports of how much people are struggling, it seems almost surreal to imagine that I'm free to do whatever I want for the rest of my life. But LBYM all those years when my income was high gave me this freedom. You sound like you've done exactly the same, and now you get to enjoy the rewards. Go for it and don't look back!
