Please help help??

Stop listening to him, stop telling him he needs to prove himself, just stop talking to him. You pick up his calls. You answer his texts. You give him hope by keeping in contact. So stop.

Well tell him everything you just wrote down... If you just tell him straight up.. then he should get it...and if he does'nt then just IGNORE HIM.. but warn him.. just warn him.. obviously he wants a challenge.. so he's immature... good luck..
