To keep or return a person, you need to let him go.
A crisis in a relationship cannot be avoided, because when one changes, becoming independent and confident, the other begins to experience discomfort. The habitual and understandable form of interaction for him collapses, which invariably leads to a feeling of anxiety and danger. The partner may panic and protest against this, provoking conflicts and quarrels. He will undermine your self-confidence, rejecting and not approving any undertakings and projects, he will criticize, condemn, ignore and devalue. In the end, he can find himself an alternate airfield and accuse you of leaving because of your indifference. The main thing is not to believe in it. He leaves not because of you, but because of himself, because of the internal conflict that has appeared. What was projected on you, now turned out to be in it. But instead of dealing with himself, recognizing, realizing the shadow sides in himself, he runs from the problem to another partner who will save him from internal growth, development and pain.
