When your heart is gone

When your heart is not into something anymore you just know things are not the same. I have recently experienced this. Mainly in the relationship/friend aspect of my life. I noticed that if I don't put the effort into hanging out with friends, we don't hang out. Friends grow apart all the time, and sometimes old ones grow back together. They say that when friends move away from you, another friend will take their place by your side. My question is, where are these replacement friends? An answer to that question is, maybe they weren't real friends. If they were real friends, then they wouldn't have left, right? I have very few friends left, I just wonder how long they will stick around. Maybe a long time, maybe not much longer. What I do know is that everyone of my friends are great people, but not everything is meant to be.
