Six of wands is typically a personal victory or something working out for you ultimately. The Moon as a clarification is interesting. The Moon is the card of intuition, but also deep emotions and the subconscious. The Moon may be telling you to follow your "gut" and intuition - and not succumb to fears or emotion as you make your choice regarding this relationship.
You stated that you felt strung along and hurt, and his past behavior has not been what you had hoped, and that going off on your own could also be seen as a victory. This tells me this is an area that you truly need to meditate on further before making a decision and I think your Moon card is pointing to that more than the relationship itself.
