Ich mag nicht: 1. Obsessiveness Constant messages, pressure, “why aren’t you answering?” — quickly tires.2. Insincerity/games Attempts to seem like someone else, manipulation, “playing to ignore” - this is visible.3. Rude or disrespectful To her or to other people (like waiters) is a very strong red flag.4. Narcissism When the conversation is only about yourself, your successes and problems.
