If you are always reliant on other people to change, you will never learn the skill of being able to create change.

Yes, It is easier if everyone around you is on the same plan, but it is not something you want to count on. It is valid to want that easy button. Many times if you start and stick to your plan, a spouse that is on the fence will join you. Your example says it all. Your ability to say no. Your dedication is going to send a big message to them.

If they don’t join you, you have shown yourself that you can stick to it, even when it is difficult. Some people may not want to eat that way or have those habits. Would you want to be pressured by a spouse? If your spouse wanted to take up a monk lifestyle but expected you to do it with them, how would that feel?

Instead of focusing on them, get started with one small change. What is something that you want to do? Break it down into manageable steps. Start with the first step.

Consider a change that you were successful with in the past. What were the skills you used to be successful? How did you approach it? What might be applicable to use now?
