Me and my boyfriend's 1st year anniversary

So I don't really have an idea what to do for him,because we did break up a couple of times now,we aren't really in a relationship anymore but....

I mean,we still are technically,but we were too young,and I need some help regarding our anniversary.

I personally think he forgot,and i need some ideas on what I should do to remind him.

(Please don't hate on the really young part,no we aren't really in a relationship just yet because we are way too young and we decided to keep this relationship as low as possible and keep it going until we're old enough,thank you <3)
