I'm not going to lend my friend cash to pay for her tuition fee
Why don't you want to lend your friend tuition money?
Because I don't like her. She's struggling with loans, and she's my friend.
She is your friend, so she can't expect to keep borrowing money from you. You worked hard for that money, yet she has been taking it from you for her own needs. She can't expect you to keep paying for her forever.
It's not like that. She is great and we are in a tight friendship.
It is actually probably more helpful to deny helping her so you are not enabling her. If it is just a one time thing then it may be ok, however if this is something that is reoccurring then it could become an issue.
