Welcome to the forums,
It is easy to get hooked. But you may want to consider the outcomes of getting another. One bird means you have a buddy who loves you and wants to spend their time with you. A second bird doesn't always mean you will have two buddies. Quite often the two will bond with each other and they will have less (if any) interest in you.
In birdy math sometimes 1+1=0
Of course this is not all the time, there are many happy owners of multiple birds. It is not a sure thing that you'll loose your buddy - but I'd say it is a sure thing that your relationship with her will change.
