Makes me Wonder

I am a really trusting person. Not like just trusting the bank statement you got in the mail or the expiration date on your milk carton but really truly over the top trusting in every aspect of the word. I have many close relationships in my life that i care greatly about however i have recently come to notice a pattern in the interactions of these relations. I feel that i am giving everything to these people, i am all in, i am going big or going home, only realize that everyone else is holding a little something back. Is this common? Does everyone hold back? Did i miss the memo? And why? Some of these people i have known my entire life, i feel more comfortable with them than i do with myself sometimes yet i have begun to realize that maybe i don't know them hardly at all. Maybe the things that they hold back from me are those of greatest importance. Maybe there are things that we just aren't supposed to know. Because by merely standing a few feet back i can keep myself from getting too close
