i need someone else’s perspective

so i’m seeing this guy. we talked aug 2020. kinda stopped talking nov 2020-feb 2021. and been hanging out since. been on many dates, one getaway to the beach for a weekend. he’s super cool about his phone gave me his code the first date lol?? i was like k. whenever he gets a text or dm on anything he shows me and idk why cause idc and i never ask! i automatically just hope people would be trustful and not deceiving. today during dinner he posted me for the first on his story. many many replies which i didn’t care about he just kept showing me. then a specific girl replied and when i looked he got flustered and just got weird. i was like huh. i let it get to me and kinda killed my vibe. once i was dropped off at home i was like “i’m sorry i don’t want to seem crazy bc im not. you willingly show me things and are pretty open. i appreciate it really. (i have never asked to see anything) but when so and so replied you got really weird.. do you have feelings for her, too? because if so that’s totally fine bc we haven’t established anything or boundaries which is fine as well.” “you know i’m not sure” “oh ok. well i know we’re not serious so it was pure curiosity honestly” “ok”

like ?? i guess i don’t know what to do? i’m not in love or anything LOL i guess what would YOU do? just cut off things in a nice way? or???? plz help, i rarely date lol. and honestly my feelings aren’t hurt i’m not mad at all bc we aren’t serious. but so do i avoid this and just move on? thank you for ready everyone :)
