argument

I would suggest that you have a talk with him to address this issue. Is he only trying to win/end the argument by bringing up divorce or is he seriously considering it? If it is an idle threat, let him know how hurting it is and how detrimental it would be for your relationship. Threatening divorce is not helpful in solving any issue and would only cause tension between the two of you. Sometimes, having a third party help work through the issues to uncover any underlying problems may help. See if your husband is open to marriage counselling.
