I had written earlier in my comment 
The memory is very old and my personal, in those days at least in our country mobile phones or any other electronic communication medium was not available.
I was pursuing my higher education living with my father. There was still about a year and a half left to get my degree.
Then in those days, we had come to another city located at a distance of 700 km from the city of my father's posting to attend a marriage with the whole family.
In the midst of this marriage, there were some such coincidences that my parents fixed my marriage with a girl belonging to the same city, a mutual condition was kept in this marriage that the newly wedded couple would not live together till I got my degree after marriage. Both husband and wife will stay together only after getting my degree.
On this condition, both parents agreed because my parents had old relations with the girl's parents. Within a week, our marriage was done according to Indian religious culture. Our friends and relatives had attended this marriage and they were quite surprised by my marriage on very short notice.
After 2 days of marriage, I returned to my father's place of posting with my parents and went back to the same old daily routine, but my life was no longer the same. I started remembering those marriage memories every day, I started remembering the words said by my wife while leaving there, when she told me that now I cannot live without you so please come soon now.
We were both at a long distance from each other and there was no means of contact with each other, there was a yearning in our minds.

About a month after the wedding, I received my wife's first letter through the postal department.
It is also important to mention here that in those days the services of the postal department were also not so quick, it used to take up to 25-30 days to reach letters from one place to another.
After receiving that letter I secretly opened that first letter sent by my wife very carefully, it was a very beautiful letter on a colour full paper, the fragrance was also coming from it, maybe some perfume was put on it after writing it, the things written in the letter my obsession increased even more, and I started missing my newly married wife a lot.
But there was no choice because we could meet only after a fixed period of time and complete my studies. Then the continuous correspondence started between us.
But if the postman was late for even 2-3 days, there would be a lot of restlessness and many hours of mine would be spent sitting outside the house waiting for his arrival at the time of his arrival. perhaps on the other side, it was the same situation of restlessness and eagerness because it was shown clearly from the letters both of us.
Well, somehow after reading each other's letters that 1 year passed and then we got a chance to meet each other.
After then I worked hard and got a government job and we both started living together. Both of us had saved a lot of those old letters, but they too were destroyed or lost over time.
(The things written in the letters of that time were very loving and childish too, but still, those things cannot be made public here because they were only private things of both of us, but remember those things even today, keep them in mind. strings become musical)
