Guys, why he responded to me after a day?

Anonymous
I texted one of my male friend stating that my ex boyfriend with whom I was in no contact for over 10 years suddenly texted me over instagram he was my first love and now suddenly he got back.

But my male frnd was online on wassup but yet he choose to reply to my text after a day which made me wonder why he responded to me after a day
