1.20 45'r: Is this always a push?

[jeramy576]

12 players left, I'm 11 of 12. Button has been semi-aggro. I'm kinda thinking this is a bad push for the reason that with him/her making it 1600 to go. They may have priced themselves into making the call. pot after my push is 5700 and only 2150 more to call which is a little better than 2.5 to 1

The results doesn't matter I'd post this hand if I'd won it. Because as soon as I did I was thinking it was the wrong play.
