too good?

Too good to be true. Does that really exist? Or is it just an expression created to ruin happiness? I'm always waiting for the bad things to come. When things suck, I feel okay, it feels normal, I'm not always waiting for the bottom to fall out. I don't know how to just be happy. It's so weird to think that people can actually be in love and have everything work out, it's weird to think people are actually happy. I just don't know if I can believe in that. It doesn't seem real. It seems too good to be true. But it's not, is it? I mean, there are people in lasting, loving relationships right? Or is it all just a front? I just have to look at my parents to know that that isn't true but I just consider them one of those rare, lucky couples. Because most of my friends parents are either divorced or not happy and none of my friends have been able to keep together a relationship, and I can't help but wonder why. Why can't people just stay together? Are they too passionate? Too sensible? Always looking for more? Which? All? Any? I'm willing to bet it's a balance between all of that, but where is that midpoint? And how do you get there? It's not like you can just ask someone how they do it? It's undefinable. Maybe we don't have a soul mate. Maybe we just settle for what we have and somehow make it work.
