To be on the fence
is used when someone is undecided about something and cannot make a decision. They are torn between two or more choices and haven’t committed to any option.

Examples:
1- Taylor Swift was on the fence about endorsing a political candidate. She didn’t want to alienate her fans, but she also felt it was important to speak out.
2- I was on the fence about ordering a salad or a burger. I went with the salad... but then added fries, so it didn’t really matter!
