Well, your relationship may not be as good as you two expected. However, you two still can make it work. Although you are honest with each other, you both are reluctant to make sacrifice for each other. As time goes by, both feel that your relationsihp is tedious. If you want to make a better relationship, both should learn to care and sacrifice for each other.
