I NEED HELP

Me and my first love have been together for three years almost , since i was 15 . A simply beautiful relationship , i loved him , he loved me . For past three months , we’ve been arguing back and forth because it got too serious too soon . A lot of pressure because we were young , but we still love each other . Last week he broke it off because he said is unfixable and we just can’t do anything about it . Yet ever since we haven’t had a day without talking to each other , more like friends now . Tomorrow we are even meeting up , and i don’t know what to do , or what is the right thing to do ?

Should i try to come back with him , if so how do i do that without being desperate ?

Or if he just trying to keep a friendship and i should just go along ?

Please , help me make the right decision
