Non-horsey husband here too. He was brought up within the Thoroughbred industry in Kentucky, with his brother being named Breeder of the Year, but no matter, he's still not horsey any more. Minis are not his passion or priority. Keeping a roof over our heads and food on the table is.
As far as the money, I purchased the horses with my money. They are my responsibility in every way. If I can't support them on my income, then there will be a problem because Hus is not going to pay for their upkeep and never has. I also work in our family business and I do all the daily chores, feeding, cleaning stalls etc. and I do not expect him to help with any of it and I don't ask. I like to be self-efficient and do things my way anyhow. The horses are my domain and I prefer it that way. I must admit that since I've been very sick these past couple of months he has done some of the feeding for me and its a wonder he didn't founder the whole herd doing it "his way." He thinks I starve them and they should be fed pounds and pounds and pounds of food
but I certainly appreciate his efforts.
When it comes time for the big stuff, fencing or building, he will step in and take over, because I will make a disasater left to my own devices, but I don't just stand on the side lines and watch him work. I have clocked a lot of time with a nail and hammer and set my share of fence posts and pulling fence lines too.
I have a bad back, more surgeries than I want to think of, and I also had a mini-stroke a few years ago and I don't have full use of my left arm and sometimes my left leg doesn't work right so I am not nearly as strong as I used to be, not to mention I'm getting OLD. So meet ROVER. We found it at a yard sale and the owner just happened to owe us money so we got a very good deal on it and I honestly couldn't do my daily chores now with out it. I back it up to my truck when it is full of feed or hay and just push the stuff onto it to be able to unload it myself. I drive it from stall to stall to clean them and it has a dumping bed. I use it for everything. Maybe you can look into something like that to help you out too to lighten your load.
You and your new husband should have talked this all over in detail pre-wedding, but since you didn't, its important now that you both talk this through and keep the lines of communication open. Write down all the chores you do and present it to him so he will be able to get a better idea of just exactly how much you do and express your concerns openly before this festers any longer because it sounds like you are about to blow. He has got to know that you are not made of steel and you need help with certain things and if he wants to keep his donkey, getting down and smelly, and dirty are all part of it. Remember, when mama ain't happy, ain't nobody happy. Good luck to you and best wishes.
