Guy's Behavior

Is it a bad sign when a guy I'm dating has not initiated any text over the past 2-3 days?

Whenever I text him, he responds quickly usually within 30 mins, but he stopped initiating texts over the past few days. His siblings are visiting him now so he told me that he was very busy with them. Several days ago, he suggested a call and we had one-hour FaceTime. It went very well, and he mentioned that he would want to introduce me to his siblings. Right after the call, he said he missed me more. However, now that he stopped initiating contact, I feel anxious about whether he still likes me or not. I texted him a few times over the past days, but his replies were short, and I don't wanna bother him while he is with his siblings. Should I wait until he reaches out to me?
