Within the past few days my LTR has followed one of her EX's friends on instagram. It's a dude who has a shit ton of followers/models etc etc. Well she liked a photo that her EX was tagged in, but is not actually in. Still, this is basically interacting with her ex bf is it not? She doesn't know that I know this, but I see zero reason for her to follow this account unless she's trying to see what her ex is up to/indirectly interact with him. Most girls do shit like this right?

How should I approach this bull shit? Hard next or give zero fucks
