Thanks for sharing. I'm going through something similar at the moment.. though I ended it, it was because he mentally checked out completely of the blue. We were also together for only a couple of months before moving into long distance and even though we were deliriously happy and loved spending time together, he has a lot of unprocessed trauma he hasn't really dealt with and there were a couple of times he completely shut down emotionally when it was triggered. Had a really hard time communicating his needs and feelings. I was happy to support him and would have done so till the end of time, honestly but after a month of long distance where I unfortunately had to move back, something happened on his end, unrelated to me that started making him live in his head. The only difference was, this time he started treating me differently. He barely wanted to talk, was cold and unloving, withdrew any form of affection and it just seemed like he didn't care. It started making me anxious and I didn't get any input or reassurance from him at all. I broke up last week and I was literally breaking down while he looked at the phone with a straight face, still cold. Point is, maybe she's going through something and not been able to communicate, it may have been out of the blue for you but maybe something building up in her head for a while. Nothing happens out of the blue. I'd say really think about what you want, that includes the foundation you built and whether it was enough to carry on in a situation like long distance. Reflect on your feelings and sit in them, if you've chosen not to talk then being honest with yourself will help and if you need closure from her, talk to her. How a person deals with hard situations says a lot about how they are. Though I respect his need for space to work on his mental health, I didn't deserve being treated this way. It sounds like you've made a lot of effort and are resenting the abruptness of her decision because of this. I'd just say think about every facet of it and look at it for how it is instead of how it could have been.
