I would of reraised on 3rd. I would of lead or check raised on forth as well. I probably might have tried for a free card and/or check raised on 6 th and check called on the river.

my guess is he had 2T)2 to start and picked up two pair
or has 2A)2 and has you on a steal or a big pair in the hole maybe QQ or KK.

did the bring bet the full bet or just the bring in?
have you been stealing much with the second high up card?
have you been aggressivly manipulating the pot/players?
were there any/many higher up cards behind you?
is your opponent the kind of player to resteal with a random hand?
