You should not have to pay for your friends. Friends should be your friends because they want to be. Not because you paid them a certain amount of money to be. That's a silly idea to even think that. Friends are friends because they like who you are, what you do, have the same interests as you, so technically, they wouldn't be friends at all.
This is what Wikipedia says
Friendship:
-The tendency to desire what is best for the other
-Sympathy and empathy
-Honesty, perhaps in situations where it may be difficult for others to speak the truth, especially in terms of pointing out the perceived faults of one's counterpart
-Mutual understanding and compassion; ability to go to each other for emotional support
-Enjoyment of each other's company
Trust in one another
-Positive reciprocity — a relationship is based on equal give and take between the two parties.
-The ability to be oneself, express one's feelings and make mistakes without fear of judgement.
-It is very important to have honesty, trust, sympathy, respect and helpfulness in friendship.
