Advice with boyfriend

When i’m with him it’s great. But the weeks are super long so we usually just text throughout them. When we text, i feel like we are just friends. I really really want more written affection. I’m starting to lose that feeling bc he doesn’t say a lot of affectionate things as he once did and i really like him:( he does like me but i feel like he feels safe where the relationship is and has no idea that this bothers me. ik i could just y’all about it with him, but i don’t wanna be a complainer or annoying. should i show him more affection and see if he does it back? what do i do?
