i cant help but overthink

so yesterday at work my crush was signalling me to eat and i replied that i was still busy with work...after i finished my task our supervisor told me to rest for a while and take a five minutes washroom break so i marked scheduled break on my system and got up from my seat as soon as i got up my crush hurriedly locked him system and came out right behind me and said lets go i was surprised and replied i thought we were having lunch with all the others he didnt reply so i just quietly followed him, he even paid for my lunch and we made aome small talks not work related. But i think he's using me to test this one girl who he has a crush on (who is also my friend) OR maybe our supervisor told him to have lunch with me...ugh i like hi m so much it hurts...but im certain he doesn't like me back 🤧
