Not every interaction will have a meaning. Shes in a chaotic place and may not understand what shes doing all the time. I spent months trying to understand W's thinking and got a good idea of what was happening, but it doesn't help me much now.
It causes you more pain and makes detachment so much harder. In the end whatever happens will happen and you're mostly out of control, its better you get to that detached state sooner and not understand ALL of her thinking.
Its better to look at the bigger picture and not every single interaction anyway. If you try to analyze every single up and down she has on that rollercoaster its going to drag you along for the ride. Shes inviting you places, accept some and show her the best version of you that you can. She may be conflicted on whats happening and that's the reason for the cold texts, or it could be a completely unrelated reason. Just because shes inviting you places doesn't mean you need to pursue her right now. Read up on the pursuit/distancing dynamics.
Accept what is, let go of what was, and have faith in what will be
