Answer:
#1; "I felt confused about my parents' divorce and had no one to share my feelings with. I'm here for you if you want to talk."
Step-by-step explanation:
This response is positive without being too sunshine and rainbows and doesn't accuse or criticize the other like the second and third response. The fourth response is almost as though Andrea is blowing off Chloe and her worries/feelings. So, to start a healthy dialogue, Andrea should say the first option. Hope this helped :)
