Is it a bad idea to try to seduce an old friend if you have genuine feelings for him?

I’m asking for future references, if I ever find myself in this situation again with another man I’m friends with. I tried once because I was in love with aforementioned man at the time and he declined. Then he told all our friends how weird I was. I’d known him for many years and been friends for 3 years at the time.

I guess I’m thinking honestly that it was a mistake to be so forward, despite thinking there was chemistry. But I am autistic and I don’t read social cues very well.
