if I was filming it for a YouTube video? probably not! she was literally just opening cards - what’s he supposed to do just sit there like “oh that’s nice”? she chose to film it I assume knowing he then wouldn’t want to sit with her. I really don’t see it as that odd, if I was literally just sat opening a few cards like she was I wouldn’t expect my boyfriend to sit there with me, I’m an adult?!But would your partner not sit with you while you opened your gifts and be there to support you as it was an emotional time anyways with the lockdown happening. He sat in his “home studio” making music next door.
I’m not sure what teen fantasies everyone’s been watching but most adult relationships don’t fill the house with balloons for a non-milestone birthday, most guys aren’t about to whip up a cake and fawn over their other half whilst they open a few cards. does it live up to her instagram perfect birthday? no. is it completely normal? yes.
