I don't think I've ever fully grokked the 'never see them again' thing. Not if they're still breathing. Anyone I want to see? I can. I love people all over this durn globe. Most I'll probably never see again, but first off that's my choice. And secondly if I really wanted to? I could. Dead people sort of piss me off, this way. Yo! You're effing up my world view here, you lazy mthrfkr! Die on me? Gah. <insert swearish rant here>. ((The irony is that half the time I just assume anyone I don't have eyes on is already dead. Saves time.))
I come from an age before cell-phones and skype. Long distance phone calls were $10 a minute, with modern numbers making that value easily twice or triple that. Writing was the only way to stay in touch, and quite frankly, I didn't. I'm a lousy correspondent. What I am good at... Then & now... Is tracking people down. I can find just about anyone. So, nah. Seeing someone again? They'd have to be dead.
Having them not be part of my life is harder, regardless of what I want. Boyfriends I've loved, friends I've loved? So many people are no longer part of my life. And that is life. Our lives move in different directions. It's right, and as it should be, but I don't have to like it.
Therapy is, in part, supposed to be practice for real life. And that's a piece of it. That great teacher, that good friend, the old flame...we lose good people from our lives. Not because they're bad, or we are, but because our lives diverge. Normal, healthy, part of living.
