Argument with friend?

[LuxeLisbon]

She messaged me to ask to borrow money.

There have been 2 instances in the past where I’ve paid for her in good faith (train ticket, concert) that she then decided that she couldn’t go and never paid me back.

I said no because of these instances and she went mad at me. Now said she can’t afford the holiday we planned to go on (nothing booked yet.)

You have done well to avoid going away with her. Because you know, when you got there, she would have no money for food, drinks, trips etc and the whole lot would end up being your responsibility with no hope of getting it back.

Go on your own.
Not travelling - find a nice cheap half board last minute deal and take some good books and music. Easy.
She's no friend.
