Would this annoy a girl?

I've been talking to this girl for like 2 months now. We maybe brought up our exes maybe once or twice in convo, but its not like constantly bringing her up, I just don’t.

Anyways, tonight we were discussing how this girl always sleeps so much. I texted and said, “ur just like my ex. She would sleep so much.” She ignored me now for hours since I said it. Would this piss a girl off? Like I said, its not like I’m constantly bringing up my ex.
