Lingering thoughts and feelings

I was able to recognize an unintentional model I use with my spouse and stop the forward motion; I paused, I did some thought work, felt differently and showed up in a more congruent way to the way I want to be in my relationship. I ended up having a nice evening with my spouse. However, when I woke up the next day the feelings of anger I felt with the unintentional model were there and strong. I want to keep showing up in my relationship in a different way, but the thoughts and feelings from my unintentional model are still there. I know I still need to process them, how do I do that? The thoughts and beliefs I have are so strong, they continue to show up over and over.
