The villain in this hand has been playing noticeably more loose than everyone at the table, but so have I up to this point. Everyone pretty much kept on folding around so I was pretty comfortable opening a wide range. Hes 3 bet my button open once already prior to this hand and ive also seen him do this against another player at the table. And mind you this has all been within a pretty short amount of time. On this particular hand I decided to stick around and my plan was to get real aggressive if i flopped anything decent. I know I messed up big time here but I dont know exactly "what" I did wrong. Should I have even been in the hand to begin with?

Also, im thinking I messed up with my bet sizing on the flop.. When he jammed I basically wanted to just die. If im going to take this line, would it have been better to jam?
Any thoughts on the hand at all would be great
