A relationship is primarily not just two people who live together. It's a whole world in which everyone fulfills their role. In order for the relationship to be harmonious and happy, you need:

The ability to listen to each other is one of the most important factors, if you do not listen to your partner, you will not be able to understand his thoughts and point of view. Try to ask questions if you don't understand something and listen carefully to the answers to understand exactly what needs to be changed or what is bothering your partner.

Show respect for your partner, his opinion, his words and advice, do not forget that each person has their own opinion and it may differ from yours.

Never compare your soulmate with other people, this can lead to conflicts and misunderstandings, each person is unique in his own way and has his own advantages and disadvantages.

Don't be afraid to talk about your feelings if you have any problems or are unhappy with something. Discuss this situation with your partner and try to find a compromise solution that will suit you and do not gloss over the problems.
