Advice with boyfriend :)

So me and my boyfriend have great trust but obviously he gets a little jealous and he is always curious on why I only keep like three people's texts but I swear to god it's just the clutter I hate 🙄 my ocd will literally give me migraines if I look at the message thing and there is like messages to like 7 + people it doesn't look right in my head. Any advice on how to tell him I'm not hiding anything it just bothers the crap out of me to have all that clutter? (Again I'm not hiding anything I promise)
