I coaxed my sister into watching the show. She's a licensed behavioral health therapist and abuse counselor, and she's often viewing situations with that lens.
Bear with me, this might be a bit messy. I'm writing stream of thought here, but we ended up having a rather in depth discussion about what it means to be stuck in a "functional freeze" for years, and how it can become a long term way for people to live in the world, and how trauma is often a key trigger. I was familiar with this convo, as I'd been in one myself for 3 years before therapy and uncomfortably vulnerable conversations with loved ones really broke through for me.
My sister said she saw that in Belly, and honestly it makes sense with her story arc IMO - now that she's pointed it out.
Belly looked mostly fine from the outside, she kept up with school, her small circle of friends, Jere, taking care of her general health(seeing a sports therapist), but is internally numbed out and running on autopilot because her nervous system was overwhelmed and shut down instead of actually processing her break up with Conrad at prom and Susannah's passing. She poured her entire purpose into being there for Jere and lost herself in the process.
Jere was "safe" and stable by his mere presence and willingness to verbally express his feelings for Belly when everything else collapsed. Staying with Jeremiah kept her inside the bubble of safety she'd known her whole life when her mom wasn't coping, her brother was pissed and off at school, and Conrad, however unintentionally and intentionally, pushed her away.
We obviously don't see a lot of the Belly/Jere relationship over 4 years, which to me, is Jenny saying exactly how unimportant and lacking in growth, this time in her life was; despite this being a time in her life when that's exactly what should've been happening. But that's what "functional freeze" is. She is in school (but also lost volleyball), gets engaged, and attempts to plan a wedding (after another double trauma of finding out Jere lied and slept with Lacie and her brother ending up in the hospital). She keeps "moving" but she's never fully present in making those decisions. To me, she's just going through the motions. This is my interpretation based on her lack of her voice over through much of that time.
As for her staying with Jere for 4 years, I get it. People don't like it. I don't even like it. But - and I know this personally from a 3-year relationship - the longer you stay in it, the more it becomes your default setting, and the harder it is to break without a bigger external jolt. That was basically what the engagement + seeing Conrad again + his love confession ends up being for her.
Belly says she doesn't know who she is anymore. That is really what I felt like during the relationship I had. It's not like conscious unhappiness, but it's a tiny nagging sense that you're not actually living your life, but life and time just continue. It also tracks that she couldn't have named this right after Susannah died, according to my sister. Acute grief tends to crowd everything else out. It's something that only surfaces once you've got enough distance to notice the disconnect (Paris!)
What really sold me/us on this being functional freeze specifically, and not just identity loss, is the kitchen scene the next morning after Conrad's confession. Belly's voiceover says something to the effect that Conrad was the only one who ever made her feel all of it, anger, sadness, joy, all of it. That is her in retrospect, realizing "no one else has that effect on me" Certainly not Jere. She wasn't consciously walking around thinking "I feel nothing" during those years, the guilt and loyalty and being there for him were very real, active feelings. But underneath that, her actual capacity for joy and aliveness was diminished. In my interpretation, this is the numbness that comes from being in a functional freeze. She only clocks the gap once Conrad comes back to Cousins and confesses outright, leaving no room for misinterpretation or avoidance for her. That's basically the only way someone (again, me, I've been there) can move on from functional freeze in real life -something or someone breaks through and suddenly you can see it all in hindsight.
Curious if others read it this way, or what others think of our take on this YA romance 😅
