I agree, when I went back and looked at the hand I should have pushed all-in there. At the time, I merely was thinking reraise and just hit the raise button without looking at how much of my stack it was. But I read the guy as trying to buy the pot, I put him on AJ AQ or AK, so I figured I was split at worst to be honest. He had limped on every hand and it was time to teach him a lesson, he tilted after this and dumped his entire stack to the table....
