I'm going to end a 13 year friendship because they called me disgusting for asking for money after helping them out
Wow I can't believe they would do that.
They're supposed to be best friends and they kicked me in the face when I was down.
When you help people you should not be expect anything in return. When you get in trouble friends are expected to try and help you out.
I'm sure I can find a better friend that won't abandon me when times are tough.
It isn't fair what they did to you. While they have no obligation to lend you money, they shouldn't pick on you for it. I think you have the right idea on trying to find better friends.
