Do you think he stopped coming in cause I acted uninterested?

long story but me and this regular customer had this flirtyness/friendliness thing on for awhile there was just a vibe and a connection there. Kind of like we’re friends ya know cause when he sees me like walking to the bus he’ll wave hi to me, smiley at me. idk if it’s just out of politeness but the last time he came in, i had asked him how his fourth was he told me he was with his brother and that he blew up his fridge, and then showed me a video of it and honestly i was so unimpressed like who enjoys just watching a fridge blow up that was when i kind of realize like wow and then i started thinking that he’s pretty cocky those times he would talk to me it would always be about him.... and now that i have a different feeling about him now idk how to act. anyway, i saw him after work that day he was just in his truck waiting for the stop sign and i wasn’t sure if i should’ve waved or just kind of ignore him.. so i chose to ignore him and since then he hasn’t been coming in. he usually comes in like once a week or twice a week so idk.
