NOT let “distance” be the excuse to end the relationship. As the saying goes, if there’s a will there’s a way.
There also has to be TRUST in the relationship.
The benefit of being friends for a long time before distance is a factor.
Communication is also important.
That doesn't mean calling each other every hour or demand text update on whereabouts or who you're with.
Everyone needs space but not too much.
Everyone is busy but you shouldn't make her/him feel that you don't have time. A simple text or a one-minute-call will let her/him know that you are thinking of her/him too.
You don't take communication for granted
Others also need to realize LDRs affect more than just the couple involved – family members and friends are affected too.
Relationship will grow from strength to strength if you put in the effort. You'll truly treasure the little things and it will make you appreciate your other half even more.
You might be jealous of others enjoying an standard relationship but if you make it through, others will look at yours with envy at the couple who truly made it through thick and thin.
BUT not all long distance relationship survive.
