How do you deal with an indecisive significant other?

My girlfriend takes indecisiveness to the next level.

She won’t make decisions about of the slightest importance, it’s as if every decision is a monumental life choice. I’m getting very frustrated. Its like the idea if making a decision exhausts her.

She doesn’t like to make plans because of her indecisiveness, because she’s afraid that when the moment comes around she won’t want to follow through on the plans. This is with me, her sister, her friends, anyone

Food— she never wants to pick where we eat

TV— she never wants to pick what we watch.

We are trying to look for apartments, and she doesn’t want to go look because that’s a big decision.

Furniture for the apartment she doesn’t want to go look because decisions have to be made.

As a man I don’t mind making some of those decisions, but it’s also annoying because she knows she has a preference, and in the bigger decisions she wants to have a say, but it’s like the idea of making a decision exhausts her!
