I feel like his jealous girlfriend would hold him back from lots of opportunities. He might feel stressed out and not able to give his best in the competition. If I was him, I probably would seek support and kind words from my partner, not this childish and selfish behaviour.
Or agr over possesive ho to fir ladke ko bolo ki wo kahin na jaaye. Or fir dono ke hisse ki mehnat or kamyabi khud hasil kro. Other saare boys se distance maintain krke
His girlfriend should understand that he doing his work should support and motivate him. Uski jealousy use aage badne se rok sakti h not only here every where in life other girls to har jagah milegi hi or hamesa hi uspe aise sak kroge to bechare ka jeena muskil ho jayega
agr esi lardki ki feelings hain tou boy s ki bhi feelings houti hain,,, agr tm apni joyness kou khud damage kr rahi hou then why put it out on the boys who wanna be joy with his work damn....
