Yeah, it sounds like she wasn’t communicating her feelings very well either. It also sounds like she might have been trying to figure things out during that time and ultimately decided that you two weren’t right for each other, without your input and without giving you a chance to fix anything… which I know feels unfair, but people do that sometimes when they’re internalizing their feelings for whatever reason. There really isn’t anything you can do about it other than to let them go if that’s what they’re saying they want and use those words as your closure.

If what happened feels unfair, it’s likely you had expectations that weren’t met here. You were expecting her to have a level of communication that she didn’t meet and that unmet expectation feels bad. I think that’s more of a sign that maybe she’s right that you two weren’t right for each other, at least not right now.
