I don't know. When we decided to get a dog, we were both ready. It is a big responsibility, and not one to take on without full consideration of what you are "signing up for"...
Ok, so you know your husband has no desire to do this, and doesn't like the way dogs smell. What are your plans regarding this? Do you plan to keep the dog outside to reduce the smell in your home? Then no, don't get a dog. Do you plan to keep the dog inside all the time, with you, and only go out when family goes out, or when you take it out to go to the bathroom, and give it regular baths/grooming? That is better for the dog and for your family.
What about sleeping arrangements? Do you expect this potential dog to sleep in the laundry room? Then no, don't get a dog. Will it sleep in your room, in a designated crate/bed, or one of your children's rooms? Then ok. Do you expect the dog to snuggle up in bed with you? Then no, don't do it. Husband doesn't want this.
Are you willing and are you able (do you have the time to devote to it, and the energy on top of everything else going on in your life) to spend time daily training the dog? Will you be resentful when husband doesn't participate in the process? When you are the one cleaning up the messes from accidents early on? Or later when the dog is old and develops incontinence issues? Or is sick?
What plans do you have for vacations and other travel? Can you afford to board the dog? Or hire a pet sitter? Are you comfortable having someone come into your home? Can you afford to pay someone to do it? Can you FIND someone willing to do it when you will need the service (summers and holidays, typically)?
Can you afford vet bills? Dogs aren't just food, treats, toys and bedding. They are annual vaccinations/preventatives (shots, plus heart worm preventative, flea/tick preventatives, etc)... An average annual vet visit for us runs around $400. And that's a healthy dog.
Are you prepared to cover additional expenses if your dog develops any chronic conditions? Our dog went into a series of major seizures around 6 years old. She's now 12. For the last 6 years we've had to buy anti-seizure medications and thyroid medications, plus a delivery method (pill pockets so she will actually eat the medicine), plus regular (a few times a year) blood work ups to determine if her dosage is correct, etc. All of this costs money. I'm guessing around $90/month just for the meds and blood work. Not including her regular food budget, or kennel/boarding, etc. Are you prepared to commit to that? Can you afford it?
Of course, those things might not happen. You might get lucky and have your dog be perfectly healthy and never have an issue until the day it dies of old age... at 14 years old. Are you prepared to still be dealing with the responsibility 14 years from now?
Like I said, I can't say what I would do in your circumstances, because I'm not you. I don't know your finances, your household, your disposition, how badly you want a dog, or how you intend to incorporate it into your family.
But maybe going through these items I've mentioned will help you get closer to figuring it out for yourself.
Our old lady (German Shepherd Dog) is 12 now. And has arthritis getting slowly worse. She is still magnificently healthy, all things considered. But getting in/out of the car is an issue for her now. So even taking her to the vet is a bit of an effort. LOVE her. The whole family does. My teen son (graduating this weekend and going off to college in the fall) tells her goodnight every single night, and greets her when he comes home. Absolutely loves her. My husband sometimes gets annoyed when she chooses to lie in the very middle of the walkway, but hates to make her get up b/c of the progressing arthritis. He loves her, too. When my daughter was 4 years old, she called her Mommy. The older we all get, the more we let her get away with things (like creeping up onto the sofa when no one is home). It's sad to see her slowing down and unable to fully enjoy all the things she once did (tennis balls and frisbees were her favorites). She can't run full out like she once did. And she tires easily now. Still the sweetest in the world.
So yes, having a dog can be a beautiful gift you can give yourself and your family. But there are other considerations. Please do consider them.

And yes, there are the unplanned emergencies that can/do happen. My SIL had a lab that went counter surfing when she was out of the room and ate a pot holder. (apparently it had some spillage on it and the dog thought it would be good to eat.) It was consumed, in its entirety, but the threads came apart and got all tangled in his intestines... emergency surgery. $$$
Stuff like that happens. Even when you are careful.
