Change- The thin line between cowardice and Fear

It just invokes curiosity in me how people change when they get a relationship. You one just completely changes for the greater good of their significant other- even if they turn completely unhappy which eventually backfires and you will get into more fights, more sobs, which you release finally is not worth it.
But!!!! a big but (BUTT) you will still stick to them come what may, in the most vehement way with a never ending confusion in your mind of not how to resolve the problem but if you leave this person with you right now, will you get another in time and will they accept you.

The thin line that called chnage the small babay step we need to take towards happiness is not easy. Th reason behind it??? its our cowardice which we hide in the sense of self pity and we term as being fearful to loose the person. The truth is we just don't want to break the routine we are addicted to. The Industrial Revolution has made our life so monotonous that we have nothing to do in life but to go to office and come back home, on the weekends seeing a movie or roaming around in the mall makes us feel complete which is utter nonsense. This kind of lifestyle has actually ruined our generation and our future is no less then hell, but as we say 'jab tak chalta hai chalate jao'.This is the reason change scares us even if we are unhappy in our current situation.
We are in habit of the same person day in and day out, who is self trained to our likes, dislikes and routines. We are scared of letting a new person in, the questions arises- What is the new person is a weirdo? what if this person is totally different fro me? (hello if the current wasn't you wouldn't be thinking about another person on the first place) What if the person totally dislikes me if he knows the real me? (WOW... this one is a keeper for you have no self esteem). The result of this cowardice is- a) a drawer full on medicines for cold, cough, fever, cervical, migraine pains. b) Washing machine full of dirty towels and hankies of long lasting sobbing and phlegm.
The problem is we ourselves are the one who like to cry and crib and like to be dictated. We our sick of making life decision, we are sick of heading towards a new direction failing and coming back that we left all hope. So when a person tell us to do this and to do that we have a hollow sense of achievement after getting the fake pat on out back.
