Phrases like "Estoy feliz de.." continued

Question

Hello everyone,

I asked a question regarding the structure of phrases like "Estoy feliz de.." when the subject is the same (myself), but I am still not exactly clear on the correct sentence structure in this case, so I am asking a new question to explain more precisely what I am confused about. I know that it is grammatically correct to use the infinitive if the subject is the same (like, "No creo poder hacerlo"), but what I am not clear on is phrases that start with "Estoy" like "Estoy feliz", "No estoy segura", etc. I believe that you would add "de" + the infinitive, right? So for example I could say, "No estoy feliz de haber hecho mal", and you would only use "que" or "de que" when the subject changes, right? And also, are "que" and "de que" interchangeable in this case?

Thanks!

Answer 1

hmmm whether it is or not the same subject, it is the same in English and Spanish.

Estoy feliz de estar aquí.

(El/ella) está feliz de estar aquí.

Estamos feliz de estar aquí

No estoy/está/estamos feliz/felices de estar aquí

If this is not the answer you are trying to get. Please explain better.

Thank you.
