Hi Noah,
She may still be unsure of what to do with this relationship.
When you texted her last week saying that you weren’t feeling the relationship anymore, you caught her off guard.
As long as she is unsure of what to do with this relationship, she is not going to want it to end prematurely.
In other words, if there is going to be a breakup, she wants to be the one that does it after a period of deliberation.
If it ends, she would want to end it on her own terms. At this time, she isn’t quite sure about what she wants to do.
When you called and told her that you thought that you spooked her after asking about being exclusive, she told you that you didn’t and that nothing was wrong.
However, her actions since that phone call have demonstrated the complete opposite. She has flaked on coming over three times in a row.
This is something that is uncharacteristic of her, which means that something is indeed wrong.
The sooner you have an open and honest conversation with her about why she has been flaking on you, the sooner you will discover whether this is a situation that you can salvage.
