Facing an abuser

I have a tricky family situation. When I go to family functions, the abuser is present. I don’t want to go any where near him, but my daughter wants to be with her cousins and building those relationships is important for her. I also, of course, don’t want my daughter anywhere near the abuser. By going, for my daughter’s sake, am I sending mixed signals to my siblings, my grown children and the abuser? I’m trying to tolerate him but it’s hard. Would love to have your wisdom on this.
