I think My trans boyfriend dumped me HELP

Okay so let me give some very important context, I am/was? an adamant lesbian. My friends were telling me to ask a friend of theirs (we'll call him john) out ADAMANTLY and super passive aggressively too "oh John has a crush on you John this John that. John can't ask you out cause he has a fear of rejection" so, I decided to have a conversation with him thinking I was gonna say I wasn't interested, he tells me that he's NOT trans anymore and her name is Jane (for privacy). Okay neat, I'm supportive of d transitioners because of the difficult social construct and genuinely that sometimes does happen (I knew a trans guy who found out she was actually a butch) and so I was supportive either way so I kinda dropped the conversation since it's be awkward. we talked for a few days while my friend kept bringing them up in passing and how cute we'd be so I figured why not. So I asked her out and we had done couple-y things for the next 2 weeks and then my friend tells me that my partner has DID and is aware of this but didn't tell me, and not only that, one of her alters is dating a different friend who apparently also has DID, this different friend then tells me my partner lied to me about not being trans cause they needed to test wether or not I could say his dead name in front of his parents cause they're unsupportive. I feel really betrayed and hurt but I continue to stay with him because it felt dickish and I didn't want to receive backlash from my friends I respect his wishes of me referring to them differently and then last month he just??? stops talking to me??? I sit with him at lunch I'm understanding of the fact I'm only dating one of them and all other stuff and he's been totally radio silent. So one day I just ask "what are we?" And he says "people" we had been dating since shortly after homecoming and idk what to do.
