Confession of Painful Realization

I recently got separated from my ex-wife after years of marriage. It wasn't about love or compatibility anymore, it was about me being a different person than when we met, and her not knowing how to handle that. I'm trans, but I've only been living openly as a man for the past couple of years. During those early transition days, I felt trapped and alone, hiding who I truly am from my wife and myself. It's only now that we're apart I see clearly: she couldn't accept or love me fully in this new skin. The guilt eats at me, was it unfair to expect her to stay with someone she didn't know anymore? And what about our shared life before, did everything change then too? Now, I'm trying to find my footing again as a single man, but the weight of those old regrets still feels heavy.
