Both of your bets looked like CB's. After your turn bet the pot is bigger than villain's remaining stack - so if he decided that YOU do not have an Ace (which you do not) he may push with any two.

Also - per Gigabet's theory - you MUST call here because if you lose - you will be down to a MEDIAN stack, but still very much alive, but if you WIN - you'll have more than double chips than most of the rest, and if you know what to do with it - it is certainly worth the risk.
