She has no friends
You always have to think about who is somebody posting this for?
If you’re genuinely in a happy relationship, you naturally have the feeling to protect that and keep intimate things private and close to you.
If any of my friends posted a Situationship to their story especially when they have a lot of followers I would genuinely question why are you posting this?
Basic woman code. Don’t post a man before he posts you. Don’t post a man that hasn’t officially asked you to be his girlfriend or be in an exclusive relationship.
You’re home sick after one day of travelling? It’s not even 8 PM. She hasn’t even been there for 24 hours.
It makes me feel bad for her. She’s clearly seeking validation and wants her followers to buy into this narrative that some man chooses her.
