Psychological incompatibility
It often happens that having lived together for some years, people lose psychological compatibility. When they met each other they were totally congenial but later they see that it is increasingly difficult to find a topic to talk. It gradually leads to quarrels, misunderstanding and alienation.
The matter is that people start from the same level of self-development but then their paths of personal growth diverge. In can be due to personal features, types of character or circumstances.
Let us imagine a situation. After marriage husband goes to work and his wife stays at home. While he makes his carrier, gets acquainted with new people, learns something new, his wife sticks at home, constantly watches TV series, reads women's magazines and so on. In this situation sometimes even a few months are enough to feel slight differences in their level of development. When a husband comes home and tells what he saw, heard, what people he met and sees that it is not interesting for her, he begin to feel his first disappointment which leads to first misunderstanding.
What can his wife tell him in response? She can tell the plot of a new serial, she has began to watch, but he isn't interested in it, he considers all of them to be the same. Gradually he begins to think that his wife is stupid and be ashamed of her. At first this problem seems to be farfetched and the idea that it can lead to divorce is regarded as an exaggeration, but life shows that the problem is rather serious and this fact makes it insidious, as people usually don't pay attention to it, but when they realise all its seriousness, it is too late.
