Hi, I'm happily married to a non-horse crazy guy, but then my interest in horses isn't monomanic, which really helps, and I also don't spend a lot of money competing, I just ride, because we have other important uses for money and because I already competed a fair bit in an earlier phase of my life.
I love horses but have lots of interests including reading, music, photography, cycling, hiking, climbing what mountains we have here in relatively flat Australia, and cooking and eating healthy and delicious food. I didn't ever think it was necessary to have a horse crazy husband, he's very supportive of that side of me but in a relationship it's nice to have some interests in common and others not. That way you also stretch each other a bit. So, for instance he proposed on a mountain climb and that was really cool, and he now handles horses when necessary, and I have started watching Dr Who, which I never did before. It's really nice when someone can introduce you to other interesting stuff you've not explored before.
The one time my husband sat on my current riding horse:
It was Halloween, and he'd wanted to go as a Nazgul. I told him you couldn't be a proper Nazgul without a horse, and this actually persuaded him to get on the horse's back for a few minutes for a photo.
I've got to say it surprised me, because the one previous time he'd had a riding experience was on my retired (and now deceased) little mare, and afterwards he said, "That was very disagreeable, like being drunk and staggering around."
But our donkeys: They are my husband's favourite animals. He thinks they are so cool!
There are countless ways to have fun, and they include heirloom pumpkins!
