Just to finish this story...
She went on holidays. Since then she stopped watching my facebook stories while she used to be the first to do that. She was plenty of times online during this time. I used to post only one or two pics per week/two weeks so I wasn't flooding.
Yesterday I just finished very important run - my second half marathon. As usual I've posted some pics about my run (cause I only share broadly that activty) and my personal best (<1:40:00) (at my timeline) ! What is important she cheered me on site at my first half marathon (6 months ago).
However she didn't react anyhow. Instead she posted today new image of herself while jumping (first one since few years). What is more I took similar shot of herself when we were in Spain. She never used it. I have given a "like action" (nice picture of her btw. :). That hasn't changed anything.
I'm sad. Even if I wouldn't like to be in a romantic relationship I would at least congratulate.
So... I think this is how this story ends.
