Analyzing the Relationship Dynamics between Sophie and Lily

In the following excerpt from a contemporary novel, two estranged friends, Sophie and Lily, come together after several years apart to confront their past.

Sophie: It’s been too long since we last spoke. I thought we were going to be friends forever.

Lily: I know, and I wanted that too, but things got complicated. I didn’t know how to handle it all.

Sophie: But we could have talked it out. Instead, it felt like you just disappeared.

Lily: It wasn’t like that! I struggled to figure myself out. I thought if I stayed away for a while, that could help both of us.

Sophie: Helped, or hurt us? I just wish you would have trusted me.

Lily: Trust is hard when you’re afraid. But I want to rebuild that now.
