religion vs. my belief

What do you do when you find yourself having outgrown your church belief?
How do you gracefully go on without being bothered by members of your church.
I am now at that crossroad, I am wondering how do I handle this one. I have
been a member of this church for over 30 years, my parents chose this religion
and I was only 4 at the time. I have now decided that I dont need it anymore.
I haven't been back for 6 weeks so far, wow, but now what? They will come looking
for me and calling on me. any ideas?? I would rather not release the name of church
so dont ask ok.
