I’m an amateur and DH and I have a small farm. He has his own all consuming career (aviation) that is also a major part of his identity, and I have supported that throughout our marriage. It’s part of his DNA. Hard to explain. But I think that’s a major reason he supports the horses so much. He understands having a “thing” that is bigger than just a hobby.
One thing that really helps with farm life is how much he loves doing outdoor projects and maintenance when he’s home and not traveling. He’s just like that. He enjoys tasks and projects… he’s not really into fancy vacations, etc. Neither am I. So we do a lot of maintenance together, and that works for us. It’s nice to accomplish something major, and then sit in the yard and enjoy a cold beer together. Or share a cup of coffee in the morning while bringing horses in for breakfast.
So I don’t think someone necessarily needs to be into riding, but they have to be a good fit for the lifestyle. DH likes the owning aspect of our farm. He loves owning land and doing all our own mowing. We’ve had a great pro showing a young horse for us this year, and he’s really enjoyed that as well. We can be at the show together then, and I can talk to him in detail about things as we watch the horse go, and that’s its own sort of shared fun. Our daughter is also showing more this year, and it’s wonderful to watch her together, and share in that.
