Looks really healthy to me. It’s unhealthy when a partner can’t recognize that they actually were at fault and try to change, but instead needs every fight to resolve with “we were both wrong”.

To add color, this is an interaction that started with one person being stressed. Expecting ideal behavior out of a stressed person is unreasonable.

You sound like a terrific Significant Other: willing to look inwards to see how you contributed to the problems the couple is having, and working to improve in the future.

Thank you. That's what I'm trying to be.

However I'm also a work in progress. I spent a long time being significantly less than terrific...
