I feel like Uzi would have felt very insecure in her romantic relationship with N towards the start of it, with N not really helping since he would leave it to Uzi to initiate everything since he was CONFIDENT that Uzi getting bored or fed up with him was inevitable and she would break up with him sooner or later. N's rocky history with V didn't help him in that misunderstanding, especially as V starts to spend more time with Lizzy, and adopt a bit of that uncaring persona.
Once he realises that Uzi is there for the long term after she breaks down and pours her heart out though, he instantly locks in. They are so happy and in love now
