need relationship advice

me & my boyfriend are currently on a break. casually scrolling through Instagram, I see his comment on another girls pictures. “🤩🤩” i am very much hurt by it, should this mean something to me? i mean we are on break, right? does it make a difference. he asked for a break but has constantly been texting me me misses me. today, was surprising bc he did not even bother to text me once & i saw the comment. am i just overreacting & over thinking things?
