Making my decisions for other people....and telling them it's their decision....

Here is another thought...
Why do I think it is okay for me to try to make decisions for other people, like I know what the hell is good for them? What the hell do I know about doing the right thing? What makes me possibly think that I am qualified to decide someone else's happiness? And why do I always do that to sabotage myself? Masochistic beeyatch that I am, it usually ends up with me throwing pity-parties for myself where I am the guest of honor and the cause of all that is wrong with my world. I think professionals would call this projecting...? (anyone professional out there that can confirm this or debunk it?.... would appreciate the info....) But I think that since I am so unsure, ungrounded, flighty and freaked, so must everyone else be. And what am I really saying when I say that I "know myself and I know what's best" for so-and-so? In the clear light of day and the harsh glare of 20/20 hindsight I'm just a big puss-baby trying to deploy some wacked out diversion tactic so I can run away. "Hey is that Bigfoot!?" - peace out - ....sadness is something one becomes accustomed to by necessity sometimes. Happiness is scary as f*ck. It is such a greater unknown. Man up! Right? I guess what's the worst that could happen if I show up for the game?....I get smooshed....well, as with everything else that can and may and will go awry: walk it off, walk it off.....
Inner dialogue: Keep running away, Marie, that's what you're good at. Or hey, why don't you stick around and play awhile? You might even have some fun.....
