Your reason for raising that much preflop makes no sense. You want implied odds with this hand.

The flop bet is very highly questionable with three others in the pot.

If you put anymore money in after the turn then you need to seriously re-evaluate whether you want to play higher than 10nl at the moment.

From your tone I'm gonna guess either you got really really lucky and someone bet like bottom pair or you hit your 2-outer.
