Thinks s/he gets paid by the post
Where my husband and I differ in terms of investing is that I prefer investing in the stock market while he prefers investing in real estate.
I don't know what you're overall expenses are, but it doesn't sound like you're hurting for money? Can the two of you come to agreement to join forces and cover your joint expenses? If so, you can each invest the remainder your "own" money however you wish. Just be prepared that either one of you could lose money. That's the reality of investing. At least you'll be diversified.
I don't necessarily see a problem with your husband investing in real estate with "his" money, and you investing in stocks with "your" money. He may have more knowledge in one area, and you may have more knowledge in another. I certainly know a lot more about investing than my wife does, only because I have obsessively been studying and learning the last several years. That doesn't make her any less intelligent or capable, she just hasn't focused on it the way I have. And it certainly doesn't mean I'm above making a mistake or two along the way.
I feel like my role in this marriage has been diminished because I my "job" of raising our kids is done, and he's home all day now after having worked for 35+ years gaining all this knowledge of the business world that I don't have.
As a Mr. Mom and house-husband, I will be the first to tell you your work is every bit as important as his. Just because you didn't get paid for it doesn't mean you didn't contribute. I'm betting you worked longer hours and had more responsibilities anyway. Trust me, I know the feeling of being underappreciated and disrespected because of my chosen "profession".
Everything seems to be very "my way or the highway" right now, and that doesn't feel like a partnership to me.
If your husband is newly retired, I'm sure he's struggling with the idea of no more income coming in. He's probably instinctively hoarding "his" money for fear of losing it in things he doesn't understand. He may even resent the money you could inherit. Retirement is a major life change.
Other than a bad deal or two in the past, it sounds like you've mostly both been on the same page during your marriage? Give it time, keep talking, and let him know your concerns. For now protect what's yours until you can both come to a mutual agreement. You've made it this far together, I'm betting this is just another bump in the road.
Good luck!
