Question about closure


Hi Brooke,
I recently had a friend just stop being my friend. She just stopped replying to my texts and calls with no explanation at all. This creates confusion for me and I find myself wondering if I did something to upset her (or made her have thoughts about me that upset her). The only thing I can think of is that she asked when we can get together (she lives about 4 hours away) and I let her know this month is really full for me. I’ve done several models to work through this and I have trouble finding closure and wonder what happened. Here is an example:
C- M no communication
T- Real friends don’t just disappear without communicating
F- Confused
A- Do models on my thoughts, post in here, “allow” the friendship to be over
R-Acceptance (is the goal – don’t think I’m there yet)

Can you assist with some thoughts that can help me deal with having no closure and accept the reality that the friendship is over?
Thank you!
Anja
