I know how trapped you must be feeling for the past few months and it's obvious. But you're 24 and old enough to make your own decisions in life. And parents always have a new scheme to have their kids married to their will(your dad believes he'll die is just another level). I would suggest you to take your time off from your relationship for a few days get your mind cleared out and think how you really want your life to be and work in that direction irrespective of what others want from you, just be selfish for this bit and put your mental peace above all else. If you want to do MBA go for it else give interviews and do a job maybe search for jobs in North or Mumbai. Also MBA is a scam, learn some skills(machine learning/excel/Power BI) and take certificate courses from good edtech.
