There are lots of aspects of healthy relationship for every separate couple. Some things which are perfect for one can not fit much for another. Still, there are several pillars which can help everyone and which lots of people can ruin slowly and spoil everything they have. Just help them be stable, and they will hold your relations for many-many years.
You should keep in mind that only collaboration works, and it works in any situation, whether it is surviving in the woods or love. So, you should always give something to your partner, and it is better to give even more than you receive, as you will launch the snowball effect. Your beloved person will feel this and will also try to give you more, so as a result you will completely fit each other and bring and receive only good and positive things.
Of course, there are two of you, but it is only you who should care for your happiness. You should make your relations joyful for you, and shouldn’t tolerate for ages if something is wrong, as the reason of being together is feeling comfortable and pleasant, not unhappy and oppressive.
Make more compliments, support your beloved person, tell more often what you like the most, as constant reminding will first of all bring mood of your beloved half and second will subconsciously make develop them even more. And be grateful for everything your significant one tries to do for you, even if first it is not too ideal, but this person really wants to make something only for you.
On the other hand, don’t be too intrusive. Being by the side and showing affection is surely great, but sometimes people, especially introverts, need some free space and lonely hours just for themselves. Without such alone time they will feel bad and even angry at you, as you will become an irritant instead of happiness.
Avoid paying too much attention to small things in your life which can spoil you. There are many situations which can grow into useless quarrel, but who actually needs it too often? If you think twice, you will in 90% understand, that you don’t need to make a mountain out of a molehill. You are a team which nothing will manage to break apart.
