So cool this worked for you Michael! I'm curious what you mean by "on board"? Were you seeking her approval to invest money in real estate? Or were you looking for her to be your business partner/co-decision maker?
I've been married for 24 years (dating/engaged for 6 before that) so I've been with my wife for 30 years. I quit my 9-5 job after we'd been married for 5 years to go into real estate investing full-time. I tried everything to get her involved. We attended networking events, mastermind groups, I shared books with her...all of it. But she never had any interest in real estate. I wanted her to be my partner in the business but it just wasn't her thing.
This frustrated me at first, but I had a friend that told me to be grateful that my wife trusted me enough to quit my job, and make important business decisions without her involvement. Sure, it would be cool to be the cute (well she's cute, I'm not) rehab couple that goes around fixing up houses like you see on HGTV. This sounds like an ideal situation and it works for most couples.
The point is if you can get your significant other/spouse to be your partner then great! It's fun to collaborate and work with the ones you love. But don't get too upset if they don't want to run the business with you. All that matters is you have their support/trust.
