We just met, so I don’t know him that well, but he was honest from the beginning. He says he’s still married because of their son, and because his wife doesn’t want to get divorced right now. Apparently, South Korea has a fault-based divorce system. TIL.
My now wife was married when I met her. Ignore these lame alarmists. If being married is a deal breaker you already have your answer. If not, just try to be good judge of character and decide if you like them.
