It's also really pains me because that is not only one of the closest friends I've ever had but also my ex, which I still have feelings for. I honestly don't know what to do anymore

Idk this whole situation makes me sad and I wanted to talk about it..
If anyone sees this, can you give some advice? :(

friend out of the blue but she can't just come to my birthday party? Or even just any hangout???? Another thing I need to add is that she claims that we should trust her and then like 5 minutes later, she goes on a ramble about how good of a liar she is??? Like dude....

at the last minute and that she can't go.... It happens to every hangout that we plan together. I wouldn't mind it if it happened only once in a while but everytime? Idk... And the worst part is she now always hangs out with her other friends just fine! Like she can just go to the mall with her
