How do I become more confident and not let women in relationships take charge?

I've realized that the reason I prefer more dominant women in relationships is because I'm autistic and doubt my decisions when it comes to other people, so i let her make a lot of decisons, since shes more normal and thus has a better judgement.

For example if she said "lets go somwhere" I might say "okay lets go to the historica section of the library and check out some old photos of the city", but if I ask her, she would say "lets go have a picnic at the park and then walk to pier and watch the sunset" So i say yes because thats the more normal thing to do. But as time goes on she starts making more decisions for us, and I slowly pull back as I just want more time to be alone.

However when I'm alone I make tons of decisions for myself and will often plan out entire events and activities on my own, as long as its just me doing those things.
