hen or egg first?

there is alot of things in our lives that cannot be explained and has no answer to it no matter how you were to twist and turn the matter...the question of whichever comes first or which was the cause of what comes next can go on endlessly...i came to realize that in looking at a certain matter especially when problems or obstacles in life arises, we often seek for the cause of it, the problem and try to solve the problem...but when it comes to matters which can be very complicated such as relationships between family, love and even friends we sometimes are unable to find the way out just like i do...it is because that the root of the problem cannot be found therefore there is no direct remedy to it...till an hour ago, i realised that whatever happened 8 months ago, i do not truly know what was the cause of it and which comes after which...was the bond between us changed at first? was the lack of time for her the cause? was the lacking of communication be the start of the problem? or was it that the presence of someone else the trigger to all these? i really cant tell and it is just like the hen or egg first question....no answer to it....stability of mind constantly is not easy to achieve, but trying and practicing it would still benefit you...
