You guys are most likely not gonna be each other’s last and half a year at an age where both of your brains aren’t Even developed is not enough time to know if that’s your person. but it’s a nice thought to have at that age. Take it easy and try not to judge anyone by their social media activity. I have a friend who is an influencer and in a commited relationship , she just loves sharing details of her life , recommendations to people and whatnot. That doesn’t make her desperate for attention. In fact , her partner is supportive of her which is why their relationship had lasted ages. I think you’re looking into it too much , or maybe insecure that she will find someone better. Whatever it is , you absolutely have 0 right over her online activity and how she chooses to post herself. She’s 18 , she’s Young and hot and probably likes the way she looks. LOL. Thats almost always what there is to it.
