1. Indifference has no place here. A cold relationship is death. If you care, then you need to protect love. As soon as you don't care, why do you need such a person? If you are wondering how your partner lives, what the person drinks, eats and what books she/he reads, this is a good sign. Interest is an important aspect! 2. Respect and reverence. If you know how to exchange energy, show attention, interact in society and in private, then this is great! Life position should be at the same level, including morality and ethics. Otherwise, the irritation grows exponentially! 3. You never tolerate violence and bad language against your partner. If you are tender to each other, give kisses and caresses, then this is wonderful. In healthy relationships, people do not use manipulation and abuse. True love has no sacrifice! 4. Confidence. You freely give each other time to meet with friends, work and hobbies separately. You don't check your phone or stalk your partner. And most importantly, you have nothing to hide from each other!
