breaking up

my boyfriend and i, well ex now, just broke up 2 days before our 7 month anniversary and im so sad... it was a very peaceful breakup but hes my absolute best friend in the whole world and hes helped me throughout with so much. we havent seen each other in 4 months bc my family and i moved and it sucks so bad that we couldnt see eachother. if you could, please leave some advice on how to deal with it. he was my first boyfriend and first love and i dont know how to work through this
