I need a hand

Hi everyone,

I'm not sure if this is the correct forum to ask for help but anyway here goes,

My website is a little over 3 years old, it's in the health wellness niche, traffic is growing steadily as is the income. Traffic 3,000 unique per month, affiliate income is steady around $900 average per month, expenses just WA, Jaxxy, WordPress, Yoast, sometimes pay people to write. I have about 300 posts in total, so all good to this point.
I had the site valued on a few different websites Flippa, Empire Flippers, the values range from $13,000 up to $30,000a huge difference I know.

My problem is that my wife and I are in our 60's our kids (adults) have finally left the house, so we got to thinking it's about time we wrote our wills, that in itself isn't a problem however it started me thinking about "what if I die before her" the last thing I would want is to leave the selling of an online business to her, i think it could be a nightmare for her.

While I enjoy building the site and watch it grow the day will inevitably come when a decision will have to be made on this monetary asset, do I sell now to avoid any hassle for her further down the line?

If so does anyone have any advice on where to sell my website? Has anyone sold an online business before, ? Can WA help?

On the other hand do I keep building the site and increasing its value, ? I keep having this nagging feeling that if something were to happen to me a lot of difficulties would arise for my wife as she would inherit all my assets.

If this were to happen is there someone out there that could take care of the sale so that it wouldn't place a burden on her?

I really want to sell the site, what would you advise?
Thanks in advance
