can somebody tell me what could i do and what caused this, one day i picked up my guitar and the bridge was like this

The bridge was replaced at least once already, at least as far as I can tell from the missing stain pattern.

The problem with replacing things fastened with wood glue is, that it basically only glues wood to wood, not wood to cured wood glue.

So best guess is the old glue wasn't completely removed before the new bridge was put on. Hence the failure of the new glue joint.

Heavy strings will accelerate the process. If you're not now, you should be using "acoustic lights" (.012 to .053), or better still "custom lights", (.011 to .052), your guitar will live longer.
