He then also has been checking my Twitter, as he wrote a tweet getting the wrong end about one of mine. Then yesterday to see if he was keeping tabs I checked his snapchat count. & when I went out with a couple of friends I created some stories, all at different times, which he looked at every single one but only had one snapchat add to his count. So he was going on the app just to look at stories or more so mine.
Why is he keeping tabs on me? He ended things with me? He's also trying to make me jealous on social media?
