6 month anniversary gifts for boyfriend

Aria

so my boyfriend and I have been together for 6 months and both of us think it's a big deal. he said he already knew what he was getting me (I did t ask for anything) and so k started thinking and was gonna get us those cute couple t-shirts cuz he always shows me a song that says I'm the jelly and he's the peanut butter. well today I found out he is planning a giant surprise that involves both our mom's (we're 16&17) and my 14 year old sister. so now my thought of a maybe gift is too small.

do you guys have any idea what to get him for a 6 month anniversary gift?

he's not into anything sports btw and we're both in very religious familes so it has to be family appropriate
