As your ex's feelings for you, how would you interpret Ace of Cups as their feelings? I see the card as 'an emotional beginning' of a seed of emotion, not yet manifested. We're on good terms and have been friends for years/keep in regular contact.
What so you think?
Being friends-of-the-heart is about more than just romance. Look at children and family members: it is perfectly possible to have a heart-tie with someone and not one ounce of sexual feeling. I'd suggest that your ex loves you in all the important ways - just not romantically.
