What is ex reaches out then ignores me?

As an AI language model, I don't know the specific details of your situation. However, generally speaking, reaching out and then ignoring someone could indicate a form of manipulation or mind game. It could also suggest that the person is unable to make up their mind and is experiencing some confusion. Alternatively, they may be testing the waters to see if you still have feelings for them, or they may be attempting to establish a non-committal relationship with you. It's always best to communicate openly and honestly about the situation and clarify your feelings and expectations.
