Cancer having problem with Leo friend

I have a friend ---- let's call her Leo. She is 8 years younger then me and i use to call her my little sister we known each other for so long------- we have gotten very close. A week ago i asked her if i could borrow her Curling iron for my trip to Bahamas and i would give her 15 bucks for letting me hold it. I told her when i get back from my trip i will go and pick up my check and give her the money. When i got back that Thursday I left the next day which was Friday to pick up my check. I told her i should be home by 3-4 O'clock---it took me longer then i thought because of NYC's crappy public transportation. When i got home it was about 6pm. I couldn't even sit down b4 she calls my house asking me" Ebb where have u been i was waiting on u to so i can buy this shirt i want, but now the store is closed". I thought it was real annoying that she did that. I told her i would call her back in a little bit because i was on the phone at the time. I wand up going to my cousin barbeque b-day party that day---he's a cancer too. When i got home to call her to give her the money; my father told me she was calling back to back looking for me when my father told her i wasn't there. Anyway, my father wand up giving 20 dollars and she told him she would be back with the 5. I give my father back the 20 and it was okay but she never returned with the 5. I saw her two nights ago and it was really late i asked her where she was going and she told me to buy some w***. I asked her if she has the 5 or did u give it to my pops she ignored me and kept walking. i then got pissed off and went in my house because i really didn't need her drama. A day later she sees me and says nothing. I paid her no mind and i have cut her off. Reason being that she did this b4 with petty money and i can't deal with her. Mind u she doesn't work so i guess thats why she acts the way she does with money. She's real spoiled. Maybe i should of just brought my own curling iron. She calls me and i don't know y but yesterday i saw her on the block with someone she talks about like a dog talking s***-- well the other gurl was---- at me. i laughed at them because their real childish but she's pushing me to the limit. I'm just trying to stay away---cause i will hurt her---seriously. was i in the wrong?

WOW....okay i have to agree with cancershorti you wasn't wrong at any point, now i know how traffic is in NYC because i use to live there, she should have never went out to stores without even having cash and it's like she couldn't wait the next day— I can't believe she was still acting stuck up even though your father offer her the money and wasn't worrying as much about the change but as being a friend i thought she would have paid you back because that's the right thing to do IMO. I think you should let this friend go even thought it's hard since you guys knew each other for a long period of time but i really see this pattern is going to continue as long as you guys are friends.
