To end it or not to end it?

Ive been datin my bf for 21 months.We're now long distance coz I had to move internationally coz of my parents.Im 16,hes 20.I moved abt 9 months ago&we've seen each other once for 2 weeks.I'll see him soon for another 2 weeks.In the past 3 months we've gradually been arguin a lot.I feel that he's over protective.This's been a problem since b4 I moved but I felt it wasnt a big problem til I moved.I love him coz he makes me laugh,he has some similar likes to me&also different 1s, hes sensitive to my needs(he has never pushed me into anything),hes a good listener&he knows how to make me happy.He would never cheat on me.eg of his overprotectiveness is,he's talked to one of my guy frnds on msn&my guy frnd made a joke about likin me abt 5 months ago.My guy frnds now dating 1 of my good girl frnds&my bf's met my guy frnd.He doesnt like my guy frnd&i went to my guy frnds bday party abt a month ago&he got really angry.Should i end this coz we argue so much?also he sed he doesnt love me as much
