Hello. Our parents often teach us very correct things, but do not take into account that the partner with whom we will have a relationship is not always patient and can show understanding and offer solutions to the problem. Ultimatums in relationships are different, those that benefit us and those that simply manipulate our decisions. I advise you to read this useful article https://wisedate.net/ultimatums-in-relationships/ which aims to help you understand what the essence of an ultimatum is, and whether it is worth making sacrifices to satisfy your partner in this particular need.
