Yeah that makes sense, though with all the terms out there these days doubling them all and adding romantic to the end is a tad bit confusing. It isn't the dancing profession that makes him look gay though, it's like he is camp but tries his hardest to suppress it. Should just embrace it, plenty of camp men are straight. Just look at Matthew!
People can be attracted either physically or emotionally to different genders. you can swap out 'sexual' for 'romantic' to make it emotionally. for example, based on the assumption that he is gay, he would be a " Biromantic Homosexual" if he had emotional feelings to both genders but only physically to men. It gets confusing and irritates people though so most people miss out the romantic part.
No idea what that means but I'm assuming you mean he'd still have feelings for her? Possibly, gender/appearance can be seen as just as formality, though wouldn't that make him bi?
Probably, but it wouldn't be fair on her at all. He seems like the type who'd get all creepy and controlling if she met another man afterwards even if he was gay tbh.
Well, if he's gay then I think it'd be best for him to come out. However he should still continue to support her financially and emotionally as he made a commitment like I mentioned earlier.
night!
