Ring or no ring, MARRIAGE still holds. The idea of returning or retaining it does not count. B4 Almighty God, u are married in as much as bride price/dowry has paid, even if there is no white wedding or exchange of ring. U don't need crowd b4 marriage is conducted, just the two families are enough. As for putting away your wife, God hates it (Mal 2:14-16). So, don't think about that.
Mr man, as for telling lies and cheating etc, God hates it too ( read your bible very well)
