as a friend,u should always help her/him,but can be in different ways.
It is said a friend indeed is a friend in need.If her/his problem is only about money,and she/he really needs money,then lend some as ur way for help,but not always.If they are always broke,there must be some other problems.That's something u should really help with instead of giving money for now.Don't u think?:)
