He's just as guilty too. An unfaithful husband is worthless. No one stole him from you; he willingly chose to cheat. If a man gets involved with someone else's girlfriend or wife and there are children involved, that's also a homewrecker.
In the past, if a woman was unfaithful or a married man's mistress, only her name got smeared and she was hated by the townpeople. Only she was badly talked by our own gender too 24/7 for years. Meanwhile the women kept excusing the men, putting him as a saint that did no wrong. Even the wife would place the mistress more at fault while the men would leave the unfaithful woman and blame her. Why was it that way before?
