A friend I've been hanging out with for about 6 months or so started about being pretty cool, respectful and fun. However, I'm now feeling like I'm being mistreated. The first issue is that she and I were due to go to an event this Saturday for which we'd both booked tickets. We made these plans about 3 weeks ago. Two days ago we were chatting and she mentioned that she might not be able to make it - there was the possibility that she might get a ticket to an event she was more interested in attending. She told me that she'd still come to the first event with me if the new event fell through. She has now contacted me to say she managed to get a ticket to the more prestigious event (for herself, not for me as well) and therefore she will no long be attending the original event with me. Leaving me to attend alone, or not go.
In addition the last three times I've met up with her for events she's been one hour late. She's not even apologized for her lateness.
Am I being a doormat here?
