is this weird?

this guy that i’ve been dating for a few months (exclusive but no title & also long distance) said this thing to me and it hurt my feelings and made me wonder…

so one of his ex hookups (the one that he would casually have sex with before he met me) would stalk me like crazy once he told her he couldn’t see her anymore because he was committing to someone (i don’t even know how she found me tbh). it died down after about a month of him & i dating but she would casually get one of her or her friends to watch my stories i guess for updates on my life. she’s young, when i was her age i definitely obsessed over a guy that i would routinely have sex with so i’m not mad at her. i made a joke about how she still checks on me and he said

“who blank? baby you’re worried about the wrong one.” which made me feel like he’s talking to someone else? and then i was like …. hahahahaha so who is the one i should be worried about & he said no one but it made me feel uncomfortable so i’m like…..
