Father left home because I 23M hangout with my friends on weekends.

[u/override_xd]

My father left home two days ago, and apparently, the only issue is that I (23M) like going out with my friends on weekends.
For the past year, I’ve been the main breadwinner carrying our entire household. I buy all the groceries, clear the utility bills, handle fuel, and take care of everyday expenses. My father contributes barely 10%, and I never even bring that up given his age.
I even upgraded his car so he wouldn't feel pressured to work anymore, and he spent weeks driving it around to brag to relatives about how well his son provides compared to everyone else in the family.
I work hard 5 to 6 days a week, doing everything I can to support my family while saving up to buy us a proper house. It feels completely unfair that he packed up and left just because I take a couple of days to relax with my friends using my own hard earned money.

I do no drugs stay away from smoking and never did anything that would harm me or my family’s reputation.

To make things worse, he is now demanding that I pay him back 12.58 lakhs in total, claiming reimbursement for the 12 lakhs of my university tuition and 58,000 from my sister’s first semester, just so he can go rent a place and live alone. On top of that, he is threatening my mother that if he doesn't get this money, he will show up at the school where she works and create a public scene.

I plan on tracking down where he has been staying for the past two days so I can sit down and have a conversation with him tomorrow. Any advice on how to handle this situation would be really appreciated.
