Sometimes it's a frickin' relief not to be in love. It frees the mind and allows you to go places (figuratively) that you wouldn't be focused enough to concentrate on if you were in the throes of a relationship and all the 'stuff' that goes along with it, good and bad. Just saying. I have experienced this myself and have watched various friends who are consumed with relationships, it dominates the landscape, leaving little time or energy for anything else. Maybe not everyone is so intense about it, and it's just us super-sensitive folks who are thrown for a loop by all the different energies.
