Relationship is very fragile thing, as far as I believe, maturity is the key element for a healthy relationship, besides it there are many other important aspects as well such as mutual understanding, respect for each other, etc.. In modern society,it becomes more complicated to build a good relationship,as maturity level is lacking among people. For example, one of my friends, he got married 2 years ago, he was just 25 years old at that time, he even did not have a stable job at that time. after getting married he started to face some difficulties in his married life such as argument to his wife, not able to take care very well of his wife etc… Before getting married I told him about all these things but he didn’t listen to me at all. I have met couple of time to his wife too, it seems that she is also immature. I found that, sometimes she starts arguing unnecessarily. So i believe maturity level is very important for a relationship where both can make good decisions for their future.
