Am i overreacting?they won’t stop fighting!!what’s the best way to calm and repair a failing tense relationship?

My friend is in a very toxic relationship, they both have been to jail for domestic violence they just can’t seem to get along when alcohol is involved, they have kids as well and I feel sorry for the kids having to see this stuff. I just had to bond both them out of jail for this and I’m really tired of being put in the middle of it, I know if I cut them off they will say I’m a horrible friend etc so I just don’t know what to do!! I’m very stressed out now!!
