What beloved are you talking about? His only canon romantic interest is Jonathan, or the brides, but I know some people see it as Mina.

Jonathan would lift it up and blush madly just from it

I do have more to explain but that’s just it very briefly.

A Dracula book I read, with sources listed, said that Jonathan is Stoker’s alter-ego, and Dracula is basically his desire to kiss men. And, there is an ongoing theme in the book that a husband must kill his wife if she turns to evil. Jonathan kills Dracula + has/had a close relationship with him

you mean Dracula and Jonathan? I have a LOT to explain on that.
For one, Dracula admits to loving Jonathan. Two, Dracula’s general affection towards Jonathan. Three, Jonathan’s gay aa descriptions of Dracula. Four, the symbolism behind it. And five, writer context etc
