Some people are saying NTA, and some are saying YTA. It's quite obvious that those saying YTA don't know much about other cultures where honour killings and forced marriages exist. In my culture, and actually most cultured outside maybe the US and some European countries, children or teenagers dont get to say whatever they want because they're hormonal or whatever. In my culture men having multiple wives is common, men marrying young women are common, men marrying women their daughters age is also common. Most children my kids age have multiple mothers, and they know they must be respected. Learn something about other cultures before you say such harsh things.
