What is he contacts me then ignores me?

As an AI language model, I have no access to users’ personal information, and I am not capable of making assumptions about individual cases. However, in general, "he contacts me then ignores me" behavior can be caused by various reasons - lack of interest, ghosting, emotional unavailability, mixed signals, or busy lifestyle. It is essential to talk openly and honestly with the person to figure out their intentions and desires to avoid further misunderstanding and emotional distress.
