I think that she was trying to make a point on how she views life now that she's mother. and that she wouldn't feel safe with a man like xavier out of jail,.
what did he go to jail for cause Brooke never went to the cops and told them she was attacked and they didn't charge him with Q's death so why did he go to jail?
Man they would have been so good together. She definitely loved him and was hurt by him and he just had to tell her he loves her and held her in his arms and they would have been the best couple
