Hey and thanks for the replies. Splitting up is never easy I know. This just feels like one part of me is ripped apart, or pulled from me forcibly. We were never really close I guess because of me, but we travelled together so much and had to depend on each others, that it really feels like I'm leaving part of me behind. It feels bad. I did propose to her that I would stop transitioning and guess my experiment as living a man had something to do with it.
I already moved away and am living on my own now. Kind of feels nice and ok, but at the same time I'm questioning what will I do here in the world, as it seems that I am alone now, with nobody to share anything with me.
I'm also quite tired of discussing with non-trans people about my relationship, which now is gone. People seem to think, that it was a good thing that we split, "as my gf might have felt as an outsider, when I start to fulfill or implement my femininity", as one person said. I have no idea what that means or why my gf as a woman would be feeling as an outsider with another woman and I'm sick and tired to hearing such things to such end that I told one person, that I stopped transitioning, just to stop discussing about trans issues.
