Processes

My sister continues to ask for my help almost every weekend. Her boyfriend breaks up with her almost every weekend when they go to the bars. It is obvious that alcohol is the main issue here because they have a good relationship but he just can't handle his alcohol. I talk to her a lot about how to not focus on the content of their arguments but the process. They drink he gets upset, he breaks up with her, she gets mad and confused, and he leaves town for the weekend or atleast for a day. He runs away from his problems all the time. It makes my sister really upset. I told her that if they are arguing about the same this which is nothing, focus on the process of the arguments. She took my advice and says it is helping. I feel like a therapist already!!
