There is an erroneous opinion that if disputes begin between people, then this indicates a deterioration in relations and the beginning of the end of love.
In fact, by avoiding conflict, we build psychological defenses by avoiding frank communication with each other.
Giving preference to omissions and closeness, we subconsciously try not to let anyone into our inner "cocoon".
This allows, on the one hand, to keep unchanged one's own ideas about the world and oneself in it. On the other hand, to please the children's desire to be good, that is, to meet the expectations of others, and hide their desires, and most importantly - unwillingness and discontent - as "bad" emotions. And then it suddenly turns out that we, and not the partner, need to change our outlook on life. And this is a painful procedure, because it requires getting out of the comfort zone.
Of course, he cannot arrange everything. Therefore, the irritation suppressed due to the unspoken negativity accumulates until a grandiose explosion occurs, allegedly caused by some kind of "trifle".
To prevent this from happening, it is even necessary to argue, oddly enough, to maintain the mental hygiene of relations. You just have to follow certain rules.
The first and most important thing has already been determined - not to suppress discontent, but to transform it into a positive one in a general conversation as a conflict situation arises. Because if one conflict is not completed, it will be transferred to other situations.
You need to speak in the "here" and "now" mode, operating with specific facts, and avoiding wording like "You always do this" or "You never ...". Because it will keep the partner in a cul-de-sac of guilt.
Refuse evaluations and comparisons, because they affect the dignity of a partner, in favor of your own feelings and experiences. That is, instead of "You are a callous idol," say "It was unpleasant for me to hear from you ...", "I felt pain when you ..." and so on.
