To Boyf or not to Boyf

Right I really like this lad like a lot and we have done things but I'm only 16 and he stopped speaking to me after a while even though we promised we'd get together but he was a dick when we stopped speaking but was absolutely perfect to me when we were okay if I delete him from my contacts I miss him too much but if I add him I get tempted to go back because he's acting like he wants me back  !! Advice on what to do pleaaseeee
