WHO decides for us?

This question is a million dollar question for me, as in my life enormous instances occurred which always left me thinking “who decides for us?” Lets take some examples:

My wedding, first it has to occur in 17th February’ 2003 but it didn’t happen as my father passed away, then it is fixed on 7th June of the same year but it didn’t happen as my Father in-law expired. Anyway it happened after all, the next year.

This is not the end of the story, after mistu was gifted to me by God , a comma was put into our life just after 6 days when mistu was admitted to Nursing for severe Jaundice. Well In any case HE , the Almighty rescues us every time but ATLAST – alas!!
Then comes my job on compassionate ground in UCO bank, I faced interview as a unmarried woman when mistu was 2 months old( as that was the demand of the rule). My interview went very well and within a month the Bank authority had to decide my postings and all . Meanwhile the Finance Minister of the Country declared that no JOB will be given in for compassionate ground in the current economic status of the country. Again a blast of fate – YES the fate the ultimate decision maker??
2 months back me and Subhas went to see a car and gave advance for the same but for some unforeseen reason which popped up later we could not buy it. There are innumerous….
Lets come out of the periphery of my life and peep out from the window for a outside view….OOOH…I could see my Uncle-Aunty they came down from Pune to settle down here in Kolkata , they thought the possession of the flat would be given to them in September the last year, it didn’t happen. After a long , tiring wait they ultimately settled down in January-this year . So here too things didn’t run according to their expectations.
Again you see this very Uncle- and Aunty are suppose to go for a tour in Uttarakhand region of our Country and every minute details was worked out, train tickets, Hotel bookings evertything was done. But it didn’t happen, though the cause is very welcoming and we all are happy for it. My didi from Canada, their daughter, is coming down to visit us. But what I want to mark here is-our decision versus mystical power’s wish.
SO, WHO DECIDES FOR US?
