you’re certainly right, i too fell like the love we feel for our friends can overlap with what one can feel for a romantic partner (i actually had this exact conversation with my best friend a while ago and she told me that what she feels for me is as intense and strong as what she feels for her boyfriend!)
i do think it can be really difficult to describe and now i’m gonna sound really stupid but every time i’ve had a crush i just /knew/ it was different than wanting to be friend with that person? 😓
