while employed i spend very recklessly - ordering delivery instead of cooking, going out a lot and paying for my friends' drinks and rides, etc. - meal prepping, as i do now, saves me hundreds per week.
also i generally insist on paying my way in relationships, sometimes even covering the majority of the costs. for example, i fully supported a manchild for 2.5 years who it turned out was lying to me about applying to jobs because he just wanted me to take care of him.
