PLEASE HELP ME WITH MY BOYFRIEND SITUATION

My boyfriend and I have liked each other since the 3rd grade and just this year in 7th grade(we are both 13), we got together. I know that dating in Middle School is not taken seriously, but i was wondering what ways could we be more like a couple that is cute and stuff, but not be in a sexual relationship(cause you know, we are 13). We talk constantly and mess with each other and hug, but nothing else has really happened, and I honestly feel us drifting apart and I love him so much(not like real serious) and I don’t want to lose him, So what are more cute and romantic things we can do together? Please keep the ideas appropriate. NO HATE PLEASE BECAUSE OF AGE
