why does it happen?

been thinking today...thinking about how much different my relationships are now than even a year ago. people i thought i'd be close to are just gone. poof. like they weren't ever a part of my life. i have photographs and memories to prove they were there...and yet there's a space in my heart that hurts a little every time i see one of those pictures or remember one of those memories. maybe i loved them too much. maybe i didn't love them enough. clearly, we've all moved forward. i'm certainly in a better place, with better boundaries...and maybe that was the point. to learn to have better boundaries, better safeguards for my heart. in moments like this one, i think - why can't we be friends? and then i'm reminded of why i don't really want that...that God is bigger than even the smallest twinge of "missing you" that i might feel...and that change can hurt...but it's good. REAL good.
