When he says he didn't want to be tied down does that mean he dont want to be with me ever?

When he says he didn't want to be tied down, it likely reflects his desire for independence and freedom rather than a clear rejection of being with you. It may indicate that he is not ready for a committed relationship at this moment. However, it doesn't necessarily mean he doesn't want to be with you at all; it could just mean he needs space to figure out what he wants. Open communication with him could clarify his feelings and intentions.
