social media and husbands... 🙄

What do you do when you see your husband adding multiple random women on his social media sites? I recently looked at my husbands Instagram likes and there is a woman on there that he was talking to that he is constantly stalking and liking all of her pics.. Wth.. If he married me why is he going through this chicks pics on Instagram and loving them? 
I'm tempted to just delete her off of his stuff, what would you do?
