I have no clue why I didn't 3-bet on the flop

After the turn, I was in check/call mode. How horribly did I play this hand?

what happened here? why 1.5sb?

flop: connected board, bet out for sure. when raised I 3-bet, when it comes back to me capped I'm worried and tossing UI on the turn.

turn: lead out

river: given the previous turn action I would just check/call as well

its what happens when you miss the BB but want to return to action before the BB returns, you post both the SB,BB to see cards

seems like an extreme case of -EV
correct?
