I don’t know if these points were being said previously, but I think since she’s been single for more than a year now, she starts missing having a boyfriend and so, had to do anything to come closer to B. in order to show on social media that she’s « perfectly » fine and back on track. Like her life was so boring a few months ago, but this closeness with B. makes her life a bit less empty, so « thank you B. for being my stopgap ».
Plus, since he seems to like blonde skinny women who are into fitness, this is « litterally » « perfect » for N. Thereafter, just to make sure B. keeps spending time with her, she has to do like his girl friends and show on Instagram as much skin as needed so people can say she is « wild » and « sexy ».
In reality, since her breakup, I think she’s been definitely lost and has trouble to find her new identity, so she tries different things before she finds herself again.
Also, the way she kept telling in her videos that she found happiness again proves she’s definitely lying to herself. Actually, if she wants to prove her community that she’s fine, it means that she’s in fact in a complete denial.
The look in her eyes shows how she’s not healed yet. She only forces herself to spend time with B. so she has something to show on social media. How sad it is!
