I constantly make errors when a infinitive follows another verb.  Sometimes the preposition 'de' introduces the infinitive as in "...decide de couper... " in the above exercise.   Sometimes the preposition  'à' intervenes as in "intéresser à".  Then there are verbs which take no preposition, for example "aller".  Finally, we have an example using the preposition pour, as in "...insisted pour payer..." in the exercise.  My question is "Are there patterns for these verbs or is it a matter of just learning by rote or just by listening to hundreds of conversations to remember the usage?" Thanks so much for your consideration. 

"I've always..." describes something that starts in the past and must surely still be going on.  How is that not the use of imparfait?  Similarly in another recent lesson, "I fell in love with..." again states a condition now (in love) that began in the past.  Yet both of these were phrased in Passe Compose.  I've read and reread the lessons on passe-compose/imparfait but they do not seem to address "I've always found... I fell in love...".  Please help, Je suis tellement exaspéré !  :-)

Should “nous nous sommes impatientés” actually be “nous nous sommes impatientées” because the “nous” refers to Noémie (female) and her “famille” (a feminine word)?
