is it wrong being calculative in spending?

i was a shophaholic. im a shoes freak . i would buy at least two shoes in a months. not just a normal shoe but nice sexy shoe which i don't really wear it because i love it too much because i dun 1 it to b spoils :D

a small gathering made by my church, knocked my senses and nerves about being shopaholic. since then i decided to save up instead of buying things i WANT coz i believe i have NEEDS to be fullfill. i managed to get my pocket filled until the end of the months. i learned to sacrifice certain things, learned to be moderate and learn to be compromise. for example, i will be using certain amount of money in weeks then towards in the end when i get money from my dad, if i still have extra money then i will be using it to buy a shoe.

unfortunately, my family financial is a bit shaking for quite sumtime now. my high school fees and stuffs. i really calculating my expenses for not being broke. i failed few tyms

few days ago, i went to buy food stock and i was like forgone some stuffs to get other stuff. someone which is closed to me said that i shouldn't be that calculative or so called 'stingy' or has the ''poor people midset'' (no offense). i was trying to explain to him, i wasn't stingy but i was being calculative so that i still have money for this few days for any emergency or for other stuff. however, he is still saying dat i dun enjoy life by spending it for my needs. in the end, its ended to be a cold war between us.

ive been thinking ways to explain to him wats actually my purposes being this way. IM NOT DAMN STINGY but im just being save up. i will enjoy spending it when im ready to spend my extra money but not now when im having financial problem.
