Where are these assumptions coming from? There’s a pretty good chance he’s gonna remain in the glass closet for quite a while and is not about to confirm any relationship any time soon. Even when he appeared to be in a relationship with a female, he still didn’t talk about his romantic life and never confirmed any partnership.
Furthermore, people need to stop assuming that they know everyone’s journey and motivations. Yes, he’s likely greatly driven by ego and career goals like everyone else in the industry. But if he really just started to date his sex these past few years and genuinely just started to embrace his queerdom then being publicly out is not an easy move, career goals aside. That is especially if he’s dealt with/still dealing with stuff like fluidity, contradictions, trying to understand his emotions and love, internalized phobias, insecurities. We sometimes forget that public figures often deal with a lot of the same shit many regular queers do.
