Annoying my bf

I feel like the way my bf texts me now has a patronizing tone lately. Like as if i’m annoying him. I feel like what I say isn’t really heard, it’s just brushed off and kinda like a chore to reply to. It gets me nervous cuz I feel like that’s the first sign of a guy losing interest in you. he says he loves me and he misses me and how he can’t wait to see me, but idk. i’m gonna talk to him about it when I see him but I guess I just want to hear from y’all if you have been through this before? it’s so heartbreaking to feel that shift and the amount of anxiety I have rn from it is crazy.
