What keeps a relationship together other than love, its the trust that the people have knowing that no matter what happens, they will always be there for the other. You can fight, you can rage, snore, fart etc, or can have others fall in love with you. But be safe in the knowledge that your love is safe in their hands, and your heart wont get broken.
What keeps a relationship safe and happy, trust and faith, and love. The trust of one person to another, the faith that they will always have your back, and the love of them and your feelings between them.
Thats my feelings, always be honest in yourself, and in your partner/s and have faith the
