Just an outsider's viewpoint here, but...
OP: If you have a successful business, financial security, and a good home life - why would you want to jeopardise it all to join the current airline rat race?
I only say this because I had a mate who was a very successful plumber who loved skiing.
His ambition was to jack it in and go off to the mountains to be a professional ski instructor.
He did it. He regretted it. he spent all day paddling about in the slush taking beginner groups when what he should have done was what we all said in the first place, which was to work damn hard all summer and take the winter off, rent a flat in France and ski for fun!
You love flying. I don't blame you! How about keeping your current business and proceed on to aerobatics for a hobby, or become an instructor?
When you start doing something you love for a living that's when the fun can start to go out of it.
Good luck with whatever you choose to do though.
