I'm going to push my gf so she finally decides on things when renovating the apartment
Why are you pushing her for a decision?
Yes, she's too fickle to decide so quickly
Don't rush your partner to make decisions. It will stress her out and it is not nice to do so.
I want to spend money on renovating the living room so she needs to decide now.
The quality of the decision can be lower if you speed her up. It is also stressing to have someone push on you for a decision. Let her take her time.
