Most Helpful Guy
He said goodbye, and the memory of you will always hold a special place in his heart.
He may hope that you remember him the same way with the tag, a little souvenir for a time in your life that you can look back at and not yearn, but just know of, as your life fills up with different events. With you in FL and him in MA, he didn't want to do the distance, because the alternative is to unite life paths (move to the same place, work in the same place, become as a family), which he wasn't ready for.
So, he broke it off. But he probably felt the relationship was healthy otherwise, and you meant a lot. Breaking healthy relationships generally hurt the most, because the decision is difficult to rationalize without any good "reasons" for disliking/leaving.
