AhsanAllahu ileikum, if a person said to another person that he wont spend so much money but he did it (Doesnt affect the other person) is this a broken promise? He did not say “i promise you”. Do the spend money become haram? (Sorry for the long question) JazakAllah khayr

Ustadh AbdulAziz al-Haqqan
Don't overthink like this, maybe the context is thay he had to spend more so he did.
