Men and women feel stress differently and manage stress differently as well.
To generalize, women reach out to others when stressed, and men seek escape. Women will seek support and want to talk about it to lower their anxiety. Men repress their feelings and might change the subject.
The key is to understand the difference between how partners react to stress. This helps us not take everything personally, but rather understand and respect each other’s coping styles. When not stressed, talk about it.
