pokerstars $10 bubble hand

[bix]

What was the correct play here after villian raised me? Should I reraise big to see where I am at in the hand or should I push in? My thoughts were that he raised me on a flush draw and wanted a free card or that he limped with AJ, KJ or a small pocket pair. Thoughts?
