I was betrayed financially

Hello everyone, I (23M) got my bachelor degree two years ago and kept looking for jobs for nearly a year, i found a good paying position in a company but it's not related to my field of studies, it was very good salary ( i was making 5x minimum wage), and very good social benefits, i liked the place the people and in just 6 months i got a major promotion with no significant salary increase but yet it will eventually open the door for growth.

I continued working there for a year. Meanwhile my dad wasn't happy at all because it wasn't related to my studies. And kept pressuring me about going for a master, i eventually wanted to do a master but thought i will just work here for a bit save money and finance my own master or Make a small business.

For info i was living with my parents and contributing in paying food/utilities ( although my parents are wealthy) After numerous and long discussions i yielded and quit work to go for a master, he promised me that he will take care of me financially ( weekly allowance)and he'll pay all of my expenses just to do a master.I BELIEVED HIM.

I quit work, enrolled in a university started the program but he just bailed on me, he didn't do anything he promised, i had to sell my laptop to continue living and to afford going to school, whenever i try to talk to him about it he keep saying it's because i had tasted the sweetness of financial freedom and that's bad, but he can afford luxurious watches and trips every week, while I'm just left facing this alone with no money at all.

So now i'm back at budgeting everything and planning meals two week in advance and having zero hobbies
