I like weird people. The black sheep, the odd ducks, the eccentrics, the artists, the loners. People who actually think for themselves, the kind whose morals are not swayed by groupthink. These people have the most beautiful souls.
If you ended a relationship and realized they didn't go looking for another person, didn't go out partying, but instead started running, training, taking care of themselves, and distancing themselves from everyone so they could overcome themselves... I'm sorry to tell you that they truly did love you.
And I'm sorry to say you let a very good person slip away, one you won't find again... not even in another lifetime.
