My ex stalks my social media 6 months after break up. And posts things I think to make me chase. I’ve been ignoring him but I’m still in love with him. What do I do?

If you are not interested in pursuing a friendship with him, block him. From what it sounds like, his posts are not helping you move on and if you feel that he's baiting you, that's all the more reason why you should block him and certainly a reason not to feel guilty about the situation either. To be honest, if I were in your position I wouldn't even tell him why I blocked him on every account I possibly could. It's none of his business anymore because you are not in a relationship... moreover, his life whether you feel that he's baiting you or not, is none of your business either. So, get comfortable with not knowing what he's up to and sit in your power by not sharing your life with him. In the end this will be beneficial to you both.

Maybe try to reach out to him without mentioning that you know he's been stalking you. Ask him about how he still feels about you and your breakup to see if there's a possibility to rekindle things. if he is still looking at your social media then there is a possibility that he wants to try to speak to you again but doesn't know how to. If you feel that you are still in love with him then there is no point in bottling up your feelings as it will just make you feel worse. Love is a feeling you should be able to express freely.
