Ok so the way I see it, the main reaosn for the black haired guy's insecurity is the blodnie becasue he has had a crush on him for 6 whole years. That is not in either of thier control but these insecurities exist regardless. And This whole "you stilkl don't trust me, you dont belekive im loyal" nonsense of a conversation is just plain pointless becaseu the black hair nad blondie has been friends for a while and during the past 6 years, as far as we know, he has been promiscious like his life is ont eh line if he does not sleep with a girl a day. And not to mention, he is conventioanlly attractive nad he has a LOT OF girls you crush on him and are willing to sleep with him ,e ven while he has a girlfiedn and they know. AND AS WE ALL HAVE SEEN, THE GIRLS ASK THE BLACK HAIR TO GIVE THIER CHOCLATES TO BLODNEI BECASUE THEY KNOW BLODNIE HAS A GRIDLFRIENDS BUT HEY DON'T CARE ALL THE WHILE THE BLACK HAIR GUY HAS A CRUHS ON THE BLONDIE SO OBVISOULY HE IS SO USED TO IT AND YOU CANNOT BLAME IT ON HIM. another thign is that he has broke n up with his grilferinds based on the fact that they did not have the level of chemistry that he wanted, in bed. SO OBVIOUSLY MR I-LACK-MELANIN IT IS GOIN TO BE DIFFICULT FOR HIM TO TRUST YOU FULKLY EVEN IF YALL IN A RELATINOSHIP, YOU LITERALLY HEARD HIM SAY THAT HE IS SORRY FOR CONFESSING AN DHE KNOWS THAT YOU ONLY DID IT CAUSE YOU ARE CONSIDEREAT. LIKE BRO HE IS INSECURE AND YOU KNOW IT SO WHY YOU PLAYIN HIM LIKE THAT, WHY YOU GUILT TRIPPING . PEAPLE DON'T CHANGE EASY AND EVNE IN THE SITUAITON THAT THEY DO, its not easy for the people around them to accepo that they have cahnged soo quick. Like the blondie is at fault for the balkc haired guy falling for him but he is repsonsible for the black hair not trusting him, he is one of the main reaosn for the blakc haired guy's insecurities. ALL THOSE RELATIONSHIPS AND HE STILL AIN'T MATURE ENOUIGH TO UNDERSTAND NUANCE. selfish pr***. Anyways my fianl thoguhts guys, take it with a pinch of salt
