Even though their interactions could lead to believe that, the context is too open for interpretation now to include these in the page in the relationships section IMO...

it could be included a small note or something that there are references in the games that point that Blaze could have some romantic feelings for Sonic (Black Knight being the most unambiguous romantic reference), but nothing was ever confirmed officially, so is mostly speculation at this point.

I believe it's fully official? it seems so, but it's officially confirmed? no not really.
