I'm younger than you and my partner and I text about things like call times, trains, odd funny things we may have seen MAYBE a few times per week. He lives hundreds of miles away too, as we're often working in different countries so it's not like we're in each other's pockets. We don't feel the need to 'own' the other's constant attention or thoughts and consequently, and he does text his best mate TONS more than me, but our dynamic is committed but open and chilled. If he suddenly wanted me to text him every hour I'd be very worried indeed or if anyone did because with the greatest respect that's really unhealthy.
