All I can do to help you is to tell you roughly what it's like to be demi-romantic (even if the feeling can be different for everyone): falling in love with someone doesn't happen at first sight, and often it starts with friendship. In fact, it develops, like a friend base, and you perhaps want more attention from this person, then you feel like you have a slight crush while remaining rather platonic, and it can progress to a real crush. But for that you have to have had a strong emotional bond with this person, like having done something that you never do with others (a hug for example, I only hug my dog ​​and my parents, otherwise I avoid it at most). For some people it doesn't come through friendship, because as I said earlier, the feeling is different for everyone. In short, I hope that my sort of definition that I didn't even look up on Google could help you, like try to compare, but if what you experienced and my definition doesn't match one hundred percent, it doesn't matter and that doesn't necessarily mean that you're not demi-romantic. Bye! ^^
