Thanks for your response.

Well, I did this... three times already? First was that extreme disappearing. I actually took a flight and went to see her for just three days. She came up with that hospital story which screamed bullsh**, but I realized I was a jerk before with my jealousy and so tried to be constructive and forgiving. We actually wrote down certain ground rules of our relationship on paper, including there won't be any disappearing anymore. It was the first (and I think only) time we had a productive talk about our relationship.

Yet a year later it happened again. At least that time she didn't just disappear without any comment, but sent a text before that she's not well and needs time for herself. But that time it was completely out of the blue; there was not fight or anything and I didn't piss her off with anything.
I was very disappointed and angry and went on silent mode myself, then actually broke after she didn't even have the guts to come back and fight. But I was too weak and went back to her. I told her again that her behavior is not acceptable and that we cannot just pretend nothing happened; that it's not gonna solve anything but will just lead to the same **** happening again. I was expecting some kind of solution or suggestion, how she wants to handle such situations in future without disappearing, but her reactions basically was along the lines of "I don't know; it's just how I am; so what do you want me to do, huh, can't you just accept it?"

I knew already it would happen again but stayed in the relationship. So another half year or so later again she disappeared. Again I was to weak to break up, and too hurt and disappointed to just forgive and forget, so I went on silent mode, hoping there would be any reaction from her end. Again, nothing, except an email for my birthday. A close friend actually suggested I should "act like an adult" and fix things by forgiving and trying to move. And since we had a visit booked already for a few weeks later I did so and called her and told her we should move on.

That visit was beginning of April, and now only two weeks after she left back home she's doing the disappearing thing again. Again it's completely out of the blue. We didn't have any fight. We just talked on the phone happily yesterday morning. I went to play golf then and texted her in the afternoon. Since then, no response from her, no read notification, no texts, no picking up my calls.

I am worried that she might had an accident or so (she went to a cancer screening the day before and had some bleeding). The next moment I am feeling betrayed and belittled again that she is not respecting my feelings, and she won't even fight and fix things.
