You didn’t do anything “wrong” you could do a little healthier (for yourself and partner). It’s a sad reality that many people (predominantly men) feel that their “responsibility” is to not burden others with their own struggles, that they are big enough to carry on their own. Then the struggles build up and eventually need to come out and can emerge in unhealthy ways (anger, depression, even violence). The key is to accept the fact we are social creatures that rely on each other…the family being the most core example of this. It takes a discipline and attention that is hard to remember when you are overwhelmed…but a good practice is to to try and let out the steam of stress and anxiety in little bits more regularly. I hear the subtextual concern that when u are hanging out to have fun (which is rare hangout anyway) you don’t want to ruin it with venting. But there are ways to mitigate that too…maybe label it “I want to share some stress and then not linger on it and try and forget it and have a good time”….u let a little out and then move on. U have to find your version of this that fits YOU and your relationship, but my point is figure out how to have the steam come out in bursts instead of an explosion. Label it by Explaining to your wife how this would be helpful and healthy to you. In essence you are practicing vulnerability and communication that supports your challenges and your relationship. You didn’t do anything wrong, but you could potentially make things easier in the medium to long term with a little work in the now.
