If it is true that you have pronounced no divorce to you wife, then she will remain your wife as before; therefore her marriage with anyone else is unlawful as per the Shariah.
Islam has allowed a man to marry four women provided the husband is capable of discharging rights to all of his wives with equality and justice.
