I feel like i see a joke or comic like this every two months.
Here's the thing, if you are unsure about the messages you're receiving and decided not to act, you did the correct thing. You were wise not to interpret uncertain signals as signs of romantic interest, no matter how clear they were in hindsight. If a woman is interested in you, the onus is on her to make that unambiguous and take the next step, because she's not the one who's advances could be mistaken as dangerous.
You did the right thing.
Good catch, I'll correct it π
