Why do you think he said this to me?

Me and my hook up buddy of 2 years were sexting late at night. He asked through text message if he could pick me up so we could hook up. My hook up buddy then called me on the phone. The phone rang, so I picked up and hung up on him; because I didn't want the ringing to wake up my best friend who was sleeping next to me. I said to my hookup buddy; "sorry I hung up the phone, I'm sleeping next to someone". And then he texted me back and said "That's weird". And then he sort of was slow to respond. Why do you think he said, "That's weird" and was slow to respond?

Do you think his response was out of jealousy?
