Pulling Goalie

I just finished a 3-vs-3 Match, and I still can‘t believe what I witnessed, omg.

My team was up 5:3 in the last 5 min of the game, Now why on earth would someone pull the goalie?? I was literally fighting against that guy to put the goalie back in.  As I had no chance while he always pulled him, the other team made the 5:5 because of that crap and in OT exactly the same situation - one of them pulled the goalie and we lost. . . . Why? Just why?

Pulling the goalie should be limited or something, this is just unreal and p*sses me off!
