does their vibe seem off?

i’ve been messaging w a potential customer for a few days about a sports bra i’m selling that they’re interested in & recently it’s started to feel a bit scammy? like one of those accounts that’s a man posing as a woman to buy intimates for their fetish who never actually buys the item?

for context, they messaged me about whether i thought the sports bra would fit them given their bra size was bigger than mine on december 1st & it took me a while to get back to them bc i had finals — which i was super embarrassed by how long it took to get back to them & said i understood if they were no longer interested but if they were, i was happy to throw in a few extra freebies for their patience. which is why they said not to stress about it, which would’ve been fine & appreciated but the “you are woman who is busy” kind of threw me off?

like i don’t want to sound ungrateful for a potential customer being understanding, but also the fact that it’s been 2 weeks makes me unsure if they’re entirely serious about buying, but i know it’s partially on me since i took a while to respond. so idk 😭 anyway, id love some opinions about whether i’m overthinking this & should shut up & be appreciative of their patience orrrrrr if their messages seem a lil off to anyone else as well. thank you in advanceeeee
