Bickering with the husband

I seem to keep bickering with my husband. I find my temper with him is often short. Small things quickly become of a point of anger for me. I know there is something underlying for me to uncover and address. This is a difficult subject as I don’t really like addressing my relationship, but I know I need to. I’m just not sure where to start. Looking for guidance on how to begin unpacking so that I can create a better result in our marriage.
