Why is my Ex creeping on me?

[Blue SKY]

I think he's become obsessed with you and that is not only unhealthy but can be scary for you. I'd block him( and his friend) on any social media sites and completely ignore him. If he still doesn't get the message then you might want to consider threatening him with a restraining order. They aren't cheap but they can give you a peace of mind and send him a message. Chances are he will go away, but you need to put your foot down and demand that he leave you alone.
