He tried to make me jealous and sends things (videos, pictures) he knows i like. He wants me to look at his instagram where he posts topless pictures and pictures of him and his girlfriend. (I didn’t add him on instagram.)
He also stalked my social media (he even told me he looked at my social media profiles sometimes).
Why is he acting like that? What should I do or what would you do if you were in the same situation as me?
