How do I get rid of Obsessive Leos. I attract Leos a lot and I can't deal with their clinginess. It's so annoying how do I get rid of this obsessive Leo guy? I always attract either obsessive or jealous Leos its annoying af. What do you do? The more I avoid the more he tries to contact me through different mediums and I can't have my space. He is just a friend and we never had a romantic relationship but his obsessiveness and clinginess creeps me out. The more I run away the more he chases me. I need my space! Any suggestions?
