Why cry over musty men

Idk anything about real relationships since i seem to have only been attracted to fictional men BUT my friends here crying over fuckboys. One of them is my closest friend, and her boyfriend was her bestfriend of 4 years. There was a time where they stopped talking since she was madly in love and couldn't control herself around him, but they reconnected :D

Yet this is a tragedy tag so it all goes downhill from here.
1)Her boyfriend would rather hang out with his gang /the leader is a misogynistic prick btw/ outside school than be wit her. Mostly since he's a mama's boi that agrees that its too dangerous by themselves.
2)she had a ,shoujo manga type beat, love rival that her boyfriend's gang is close with and would go eat hotpot together. The boy literally had a crush on the rival before... them being together is damn sus.
3) After not meeting for 3 months of corona, they still dont talk that much

After many attempts, He finally admitted to not liking her and just let it off everytime they discussed it cuz he felt bad :( boohoo.
He even tryna make it like it was for her sake? so she doesnt khs ? Gurl be glad you dumped his ass.
The rival's friend grp even came along to mock her. How much of a low life do u gotta be.
