Measurable goal for 2019

Hello there! I started the homework, but I have an issue to make my goal measurable. I am currently in a relationship and I have a hard time managing my emotions and having a “peaceful” relation. My goal would be to be in my ideal relation: knowing that we won’t argue or sulk every week, be able to go on vacations and knowing there will be no anger or conflicts. How can I measure that, as all my criterias seem subjectives. Same goes with the 25 epic fails, would an example will be, going on a week end planning not to argue, and still ending up arguing? ( cause we already do that A LOT haha)
Thanks for your help
