Accept the unsolvable
Relationship conflicts are constant problems and these issues will keep revolving around you no matter how long you’ve been together. If you find a problem seems to call up painful emotions, you’re looking at one that’s persistent.
To stop this trouble from ruining your relationship when your partner is talking, your job is to listen, be nonjudgmental and to find something in his/her viewpoint that makes sense to you. When it’s your turn to talk, they should be doing the same thing.
