What is ex responds then ignores?

When an ex responds then ignores, it often indicates mixed signals or confusion on their part. They may have reached out due to a momentary desire to reconnect or reconcile, but then quickly backed away when faced with the reality of addressing the issues that led to the breakup. Alternatively, they may be trying to keep you on the back burner as a backup option in case their other pursuits don't work out. In either case, it's important to take their behavior with a grain of salt and focus on your own well-being rather than getting caught up in their fleeting attention.
