Domestic Violence

Last night, one of my neices came begging their uncle to come to the house. Her mom and boyfriend were fighting. Apparently, the oldest child got thrown by the boyfriend and she hit the wall. What I am not understanding, is why they keep playing this game? The police were called out. This is the third time the cops have been here for this mess, since I have been living here. My sister in law and her brother are not on speaking terms, but she insist on calling when the boyfriend is beating her tail. I told her after the first incident that she need to put the kids and herself first. I washed my hands of it when she let him come back the first time. He isn't working and isn't trying to find a job. When he has money, he spends all of it on weed. They both claim to be pot heads. I have told her time and time again that she doesn't have her priorities straight. She dropped her 3 kids off around 11:30 last night to take out a warrant. Deep down, I know she wasn't going to take out a warrant on him. She was just wanting to go out and couldn't be truthful about it. She came back around 3a. I tried to keep my cool, but I had to let her know how I felt. I will give this mess a week and he will be back. This is a viscious cycle that she insists on encouraging. I am not having any part of this drama.
