I should be in bed, but ilu guys

I'm trying to lead into a start of personal growth for both characters, but I feel I failed at doing so this post. So I'm going to try to explain some stuff.

What Nick heard was:
"well you've been a dick your whole life, even when you were a kid"

That's why he said what he said to Sabrina. He's only 23 and she mentions him doing what he wants for two decades. It feels like an unnecessary jab at his childhood. He has a troubled past. Honestly, the comment kind of bothered me, but I decided to try (and failed) to use it as dialog fuel, instead of asking about it. He's unsure of Sabrina's motherly motives now.

But he still sees Thierry's (lack of) reaction (crying) to Sabrina and trys, albeit poorly, to acknowledge that there are other people who need Thierry. That he can't have Thierry all to himself. He's always been a very selfish and immature person, but he knows this and wants to change. He feels unwanted and alone most days, but is aware he has unresolved childhood trauma. He feels he's trying, but failing everyone around him.

So that's why he gives the ring to Eli. Sort of a symbolic backwards way to show Eli that, despite how it my seem, that Thierry does care and that he cares as well. And as well as thinking she would want it because her mother wore it. Nick kept his mother's locket after she passed. Thierry wears it now. 

Sabrina could have just given the ring to a pawn shop, but she's shoving it to Thierry in front of Nick. Why? Thierry never stopped looking for the girls and even got his husband to help him. Sure Thierry doesn't love Sabrina, but here she is hitting him both physically and emotionally. Just give the ring away.

Despite knowing or acting like she knows of Nick's abandonment issues, she symbolically abandons Thierry. In Nick's mind, Sabrina didn't just calmly divorce Thierry and leave. She abandoned him, blamed him for everything bad that ever happened and dragged it on even after he married Thierry.

His initial reaction of not liking Sabrina is because he's jealous. But he's no longer jealous of Sabrina nor the kids by the end of the post. If he'd still been jealous, that ring would have ended in the harbor. He was jealous of her age, and her classy sense of style, specifically, as Thierry and Sabrina are older than him and he feels that Sabrina presents herself better. He feels out of place compared to Sabrina.

I don't know what else to add at the moment, so I'm gonna shut up and go hide in a blanket fort
