@Christopher Lane. Chris, some of the things your is saying are completely reasonable because people are usually fearful of what they don't understand. Some of the things she is saying are negative comments people should not say to each other who are in productive relationships with open lines of communication i.e. "I don't know why you're so obsess with this" or "why can't you just be normal" There are two separate issues. The first is finding a common ground on your finances, she needs to understand investing. The second is for her to understand why you need support in this.
Any good relationship is about solid communication and support. Financial problems are one of the most likely causes of relationship problems. So it is very important to align your financial goals and risks. If she doesn't understand the benefit of real estate (and you're successful at it) I would suggest asking her to start by reading "Rich dad Poor dad." If you've ever read the book She sounds like a "poor dad." That will give her a good foundation to understand the concept of money. While there is nothing wrong with working a job for 100k, if you desire financial freedom it will never happen from just having a good steady paycheck. Maybe she does not desire financial freedom, but that's something you may have to compromise over. My gut is if she doesn't understand why this is great, then you haven't taken the time to explain it well. Real estate isn't complicated to do or explain, it's just a lot of work.
As far as the ladder problems, I can only comment on what you've written. I have no idea what kind of partner you are. Assuming you are a good one, the things your wife are saying to you as not productive, but that's in the context of you being a great supportive partner. Of course we want an honest and open relationship and you want your partner to be truthful with you, we don't want our spouses to be "yes men (or women) and tell us what we want to hear. But instead of saying "I don't know why you're obsessed with this" A great partner will support our passions.
So you need to ask yourself is your wife not being supportive or are you so obsessed that you aren't performing your duties as a husband causing her to be discontent?
Warmest Regards,
Chad
