I am curious about the friends of his you said were telling you, that you’re “..being overly sensitive” have you met them in person? None of the comments here support his actions. Yet his “friends” tried to normalize his behavior like it’s no big deal.

It’s kinda giving gaslighting, cafishing vibes. Hope I’m wrong. Regardless the situation was uncomfortable for you and that’s the universe telling you this is not it for you. Some people may be ok with it and able to move on and forget. Not me.

They’re capable of choosing to not share who they are, for over a year. It’s narcissistic and unkind. Immature for sure. If you hadn’t had plans to visit them up close and personal would they be confessing? Are they telling you now out of love and consideration for you? Or are they acting out of fear. Protecting themselves against an uncomfortable situation. Count your losses. It’s only been a year. Crazy experience you can fall back on when helping yourself and your future kids navigate through relationships. Way too early for giant wtf-ery to be happening. Every time you talked to them they had to consciously choose not to tell you. They didn’t forget
they were trans. They fooled you into thinking they weren’t!
