This is not the reason. Based on research, waifu that had relation with other guy is the same reason as husband that had relation with other girl. They can't blame partner coz they didn't check and confirm everything matches before getting married. Some men married because the waifu pretty when the men muka penumbuk. Some women married men that they don't really like but because the men have stable income, carreer, wealth yet ugly. After being together and getting bored, either 1 or both would find someone else.

For TS video, the guy can't accept facts yet wanted to punish waifu and her lover. Worse is he brought son along which is very wrong. He should ask waifu whether she still wanted to stay or divorce, what is her plan. Simple as that yet he dengki brought gang and son to beat waifu lover and shame the waifu rather than take it like a man. He's no difference from those PRC waifu or Viet waifu that went after mistress resorted to beating and shaming.

I have seen few guys under similar situation. 1 of them a triad leader, they all handled professionally and wished their gf/waifu all the best. They didn't beat the lovers up despite having much experience in fighting , they know their partners no longer love them due to not match. They said divorced better than end up with wrong pair, at least they have chance to get someone match better

Care to share the story when you all barged into the room. His wife nekid? The lover matches the wife more or your friend matches wife more? How old are the 3 of them?

May guys think they owned their wives when married. That's why those kiasu guys condemning wives like mad when they had affairs.

Coz their belip law doesn't plotek the female in this situation. Most cases the wife got divorced and get norhing or the husband marry mistress as 2nd wife.

Cains wife gold digger married guy for money only bring gang to beat up mistress but doesn't dare to beat up hubby.

They think they are still stuck in 100-200 years ago where wives are like slaves of the men they married. Adulteress punishment cruel towards female offenders where they were made to die a slow painful death.

Situation like this, the guy just need to gather evidence for easy divorce winning custody rights if he still wanted the children and avoid paying alimony reducing the cost of divorce.

The wife had affairs with another guy could be due to few reasons only:
1) they got married out of blind marriage or parents arranged without knowing each other, never dated understand each other.
2) marriage out of interest, benefits such as for money, stepping stone.
3) keep an eye shut when found out things not compatible or not good.
4) many just don't bother to check compatibility, guy wanted pretty, girl wanted rich.
5) guy mati pucuk

So at the end, they'll breach a point where 1 could no longer tolerate and get someone else.
