Everyday I stop myself because that there's nothing for me at the other side of that bridge. Your success is based on the bridges and happiness you build. Know when to let that bridge burn& stop trying to save it.
You're a different person now, it's just sad because I miss you a lot. Strangers can become best friends just as easy as best friends can become strangers. Friends and family members evolve over time, we all do, so this is a sad but true fact of life.
