Does No Contact Work After a Short-Term Relationship? Do They Always Come Back?

I’m trying to process a short-term relationship that ended out of nowhere, and I could use some advice or insight. It lasted about a month, and while it wasn’t long, I felt there was something real there.The person I was seeing seemed avoidant—she’d get close and then pull back, almost like she was afraid of fully connecting. Out of nowhere, she just snapped and ended things. There wasn’t a big fight or anything, but the sudden shift left me feeling blindsided.I’ve been looking into the no-contact rule and wondering if it’s the best move here. Does no contact work when someone is avoidant, or do they just shut down completely and never come back? Honestly, I don’t know if I’d even want her to come back—it’s more about trying to understand what happened and figuring out how to heal. Has anyone else dealt with something similar? Did they eventually reach out, or did you find it was better to just let it go?

I’d love to hear your thoughts or experiences. Thanks in advance.
