I have had many break-ups in my lifetime, having been single until I was 39. But I can honestly say that not every break-up sucked or even went sour, for that matter. I've had some great break-ups, in fact. In those cases, we talked and came to a mutual decision, and it was sad but not a mess. Sometimes all that stuff that builds up just fades away, and isn't important anymore. It is possible to move on without lots of drama, pain, and grief.
The world opens up... when you do.
Oh, oh, can't you see? Love is the drug for me. ~Bryan Ferry
