Scorpio confused by pisces

I am Scorpio woman in love with a Pisces man. We have known each other for about 10 or so years. Four years ago we dated and it was intense on so many levels, spiritually, emotionally, physically. Then he up and left - moved across the country and told me that in another time and place we would be better. He said he had to go "figure himself out". I was devastated - felt like I lost a limb. I was bowled over with emotion and I was dumbfounded because even though we had known eachother for about 10 years and ran in the same circles, we hadn't been intimate for that long - only about six weeks. I was amazed at the depth of my sadness and intense feelings of loss I had when he cut me off completely. He called me a year or so later and apologized and then that was it. Until about a week ago. He is visiting town for a while before he moves back out of state and we have been seeing eachother again. I was so angry at him for what he did the last time and was very suprised that my feelings for him still exist and are overflowing in their intensity. We have such a deep connection that we don't need words to express. We have been having a great time and now I feel him starting to pull away - I feel it intuitively - he calls me every day and we see eachother once or twice a week while he is here but I feel a disconnect. help. I am so confused.
