hearing the word relationship is a very sensitive word for the couple, so for the understanding of the person is different little misunderstanding will have its own impact
but everyone has their own way of keeping good relationships
I think the most influential in a relationship is trust, of a trust can arise and effect on other attitudes such as loyalty let alone people who do LDR
next it is keep in communication every day and if your relationship LDR at least twice a week or 3 times do good communication
do dating once a week with your partner so that your relationship will be more tightly and harmoniously
