How would you guys feel ....

So there is this friend that was suppose to bake for you a cake on your birthday, you even got the ingredients for your own cake. She baked the cake but ended up burning it in the process.... months have gone by and she has baked other ppl stuff such as cupcakes,cakes,cheese cake. And for her birthday you spent over 500 so that she can have a good birthday and you mention it to the girl that your still waiting on your cheesecake and her response to that’s is that the other ppl she baked for paid her to do so because she needed the money... how would y’all feel about that ? I’m so upset and then she has the nerve to get mad and say bye idk about y’all but I feel like it’s time to cut this person off for good
