Your marriage/relationship can be saved if both people are actively trying to turn it around by working on themselves.
This means putting down boundaries, respecting each other, showing unconditional love, forgiveness, being aware of your tone of voice, body language and content of your words during conflict, being transparent to cultivate trust, romance and date nights.
Being patient with each other. Putting in the effort to work as a team and validate positive changes.
Remember to listen during conflict and don’t be quick to shut the other person down. Validate their feelings and perspective.
If the effort is not made in the relationship changes can not be made.
