Welcome. I am in a very similar situation. I already live in the country though. I have almost 2 acres of garden and 2 dozen chickens. My wife feels that I dedicate enough time to this, and doesnt feel I need to expand and work on a silvopasture of my 6 acres of wooded lot. I was raised in the city and have only found this calling in my last few years in the country. My only suggestion would be to start small and make your partner a believer. I recently made a fritatta from fresh eggs, tomatoes, spinach, and peppers. She swears that she has never had anything so good. She is slowly starting to realize the value of homegrown and fresh everything. Eventually I believe she will cave and agree to buy the adjoining property and start expanding. It is a very scary venture to try to take the leap and leave a good salary, so I understand her hesitation. I really believe if you start slow and prove the merits of that lifestyle your husband will come around.
