OP
No offence and I'm sure you are not like this. Please, heads-up, don't fall for the charms of a sweet talker.
As you said, you are lucky and its easy to get bored, I do. We don't run a business never have done but me and my OH left work at just over the age of 50, now early 60's - I get bored - FRI, we have our own place, its a nice, lovely place and a couple of rentals/houses all paid off and what many see as nice cars.
We have lovely GC living on the same road - we help them out but love that - we got laptops, tv's, don't do many hols abroad due to sky high travel insurance as now many medical conditions but thankfully we can do what most able people can do but less off - I get very bored and being bored and meeting someone with sweet talk can catch one off guard
Just look at it like this and as you said, you are lucky and everyone gets bored. However, get a hobby as others have stated or do a holiday that you never though of, possibly asking, mountain cliblemins, sailing, etc etc or something more simple close to home, like painting, or helping some charity etc - but never forget you are lucky and you have a lovely family inc DH
