am i overreacting – my boyfriend thinks my job is inappropriate

posting on a throwaway account me and my bf have been together for nearly 9 months and he has never shown any signs that he was bothered by my job before this

I’ve been trying to get in touch with him for nearly a week now and i’m hearing nothing back from him even though he has been posting on insta so I know he’s just straight up ignoring me

I really don’t understand why he’s acting this way and then to insinuate that i could be cheating on him, he has never acted like he’s had a problem before so i’m just confused
