boyfriend (i need advice)

so i have been dating my boyfriend for a year and a couple months, we’re in high school we’re both seniors but i am so in love with him, i put my all into our relationship 24/7 the problem is is that he doesn’t. I want this relationship to work out so bad im so heart broken because recently he has been so distant from me but denies it every time i bring it up and he never makes time for me and is always playin his stupid ass video games, i know this sounds so childish but i just really don’t know what to do at this point... do i just give it time for him to grow or do i move on and attempt to live on without him:(
