I don't think it's just women like this because I dated a guy who was the same way and it drove me NUTS! Your post actually gave me flashbacks.
He couldn't make a decision about anything to save his life. And he'd do the same thing your GF does:
Me: Where do you want to go eat?
Him: I don't care.
Me: OK, well let's go to the Chinese place.
Him: Wendys would be nice.
Me: OK, do you want Wendys?
Him: I don't care.
Me: OK, Chinese place it is.
Him: But I really want Wendys chili.
Me: (getting frustrated) OK, so are you saying you want Wendys?
Him: It would be nice.
Me: Well, why didn't you say so in the first place???????
Conversations like that happened about EVERYTHING and it drove me INSANE! And the constant waffling made it hard to have a conversation--so I can see how you would have trouble talking about the election.
My advice is if you have any doubts or are "looking for a reason to breakup" then you should just breakup with her already. If the relationship was right then you might still have some qualms about committing, but you wouldn't be irritated or annoyed with her.
The RIGHT person isn't going to screw you over.
If a guy acts like this, there is something seriously wrong.
