What are some signs that your ex stalking your social media?

[Anonymous]

If he likes the pictures you like and if he accidentally likes a picture of you from a century ago and I'm not sure if that works but there are apps that can show you who goes into your profile? But I'm really not sure about the last one so yeah. There are really little chances that you will find out because I've been stalked and I never found out until my boyfriend told me 😂
