Why it's not worth resolving relationships through letters and SMS

What happens when you convey most of your emotions to each other in writing? How to express love and passion, care and tenderness? Text messages can only clearly and effectively convey indifference and dryness. Research has shown that if a couple overuses communication through messages, the quality of their relationship deteriorates. Resolving relationships and solving problems through correspondence is even more discouraged. The only advantage of such personal confrontations is the opportunity to write an angry letter, then delete it, calm down, and forget.
