A friendship thrives on equal give and take. If a friend has to put significantly more effort into the friendship to keep it alive, something is wrong. If a friendship has become one-sided, you shouldn't just accept it, but actively do something about it.
If the friendship is only based on one-sided endeavours, it's time to talk to your friend about it, find a solution together or, in the worst case, accept that the friendship is over. Under no circumstances should you allow yourself to be forced into a one-sided active role for a longer period of time. A real friendship signals interest from both sides. Even if it happens that one of the friends is temporarily busy elsewhere and therefore has less time for the other, this should not become a permanent situation.
Communication is the key to solving many problems. Talk to your friend about how you feel if he/she never calls you first and all contact is organised by you. Don't be reproachful or aggressive though, because the reason behind it may be really harmless. Give your friend a chance to react before you judge him/her.
However, it is important that the other person knows how important the friendship is to you and that you value continuing it. If your friend is genuinely interested in the friendship with you, he/she will make more effort to not lose the friendship.
Work together to find a solution to the one-sided friendship. Try to be understanding of the reasons that are temporarily taking more priority in each other's lives. You must try to make time for the two of you despite new life circumstances, even if it's only once a month.
If your efforts don't work and the friendship remains one-sided, you'll have to come to terms with letting them go. Sometimes friends grow apart when life circumstances change and you no longer have enough in common. Don't cling desperately to a failed friendship, but look for new friends if your friend doesn't show enough interest and initiative to maintain your friendship. Try not to be bitter, because the same thing can happen to you in reverse.
