“we need to talk”

Me

so i’ve been with my boyfriend for a month or two and he sent me a “we need to talk” text last night. this past week he hasn’t been texting me as much and we haven’t seen each other at all because he’s always too busy. i don’t want to jump to conclusions, but what else would he have to talk to me about in person that he couldn’t do over text/call? please tell me i could be wrong about thinking he’s going to break up with me

(he’s 18 and i’m 15, just to help you understand the situation better)
