Avihitham that shocked me

Guys I'm literally like salim kumar from happy husbands. I don't know whats happening. So the story is there are three people and thses three are my friends. 2 girls and 1 boy. Let call the boy m, one girl s and other girl r. So the story is m had crush on s from first year. So setting her up, it took him around 1 year and for that r helped her. All these were friends and these two girls were like besties for life. It all happened in 3rd year when r started doing a part time work as a casier in a shop. So her shift ends at night 10. So that time some of us used to pick her up from the shop. One day m went there and somehow they ended up kissing. And they started avihitham from there. They had sex for six months straight from that day. One more thing is m and s were roomates. The irony was that both were cheating the same person. During this avihitham days they acted like friends and he(very rich) used to give her gifts. But none had any doubt.. Even s. But she was jealous. After 6 month something happened and m and r started drifting apart. M tried to keep her(as a keep) and she went away. At first m started to complain like what did he do and all. That mf want to keep 2 chick. But it didn't work. So he started slut shaming her(btw she is) to everyone telling that she's having affair with multiple people at same time but she had only affair with this mf. Now they are not friends.

Sometimes i don't know how mind of these people works. We are supposed to look after ourselves and have fun with with people around us. But these f*ckers are likw manupulative. I was friends with these peole and ended the company when the college ended. And also this s was a good girl. But she changed and she lost her character. Then i remembered thee banana talk-'mullapoombodi ettu kidakkum kallinumundoru sourabhyam'
