Hi, I'm Bob.
Skip the photos, I'm no George Clooney clone, but my profile is long, honest, and all 100% truth.
Would I be the sort of widower that can actually find a pretty woman to spend time and less-exertive activities with?
I have a nice cuddy I/O boat to sleep out on the water on - that should give me a few extra bonus points Lmao.

Profile in itself is fine.
The 'but' is in the facts that you can't change, not at this moment anyway: you have nothing to offer a woman as you already had the one & only love in your life and recently lost her.

So a woman has to give up on her dreams and the hope of finding new love, and be happy she gets the chance to play second fiddle in your life.
You expect a woman to settle for crumbs because you can't deal with being on your own?

That's what you're asking. No offense, but that's immature and selfish.
Since you recently lost your wife it'd be best to wait a while before going on a dating site.
You've got to find your own feet first.

Trying to get a new woman to use her as a stopgap isn't going to take your pain away. You'll have to work through it regardless. And it's mean to use another person.
