I think i broke my BG-E2N

Get a backup?

To prevent the problem in the future, the solution is to leave the grip attached all the time. Tighten it once and forget it.

You do NOT need to disassemble everything for routine cleaning. In fact, "routine cleaning" every week (beyond a simple blow-off and maybe a wipe-down if you've gotten dust all over the outide of the camera) is silly as well in my opinion.

Havent taken it off since i put it back on.. and dont plan to..

I didn't plan on removing it, in fact I never did until my 40D hit the edge of a slab of stone (with my 70-200 L IS attached)...I almost cried! So I tried to remove it to send it in (40D) for repair and it wasn't coming off, so after some effort I think I caused some of the gear stripping.
