Am I overreacting or do I have a right to be irritated
So I (31M) have known this woman for a few years and have been into her for a really long time. We had some life circumstances that kept us from being more than friends until recently where we have gone on a few dates. I wake up on a Friday to get a text that this person is going Mia, and not to text them. We have group texts with a few other groups, and the moment someone texted something important in these chats she responded immediately to them. This really irritates me because this "mia" situation now really looks more like the goal was just to ignore me for the weekend.
I confronted her about it yesterday and didn't get any answer as to why she had to go Mia, and was just told "Aren't I allowed to have time to think?" And that she had to think about things. She tried reaching out today but honestly I cut the convo short because this whole situation is just bs to me. I am prone to being a bit insecure so I know to take time to process emotions before making decisions but this honestly seems shady and I feel that if the roles were reversed and I did this to her she would not have taken it well. Can I get advice on the situation?
