So far you have played the hand fine. Pushing pre flop is just plain dumb advice. 3XBB is pretty standard and as 1st to act shows you do have a hand to be respected unless you are a LAG and known to be one.

BB has decided to call and you have now been C/R. As you are both the big stacks give him some respect here. He either has you dominated or thinks you are on a bluff and is testing your resolve. At this stage you must have some reads on the villain and this would influence my decision on whether to fold or push.

Thinking of the range the villain may be on I think a shove now is correct.
