I don't know why did you call this 3bet, it's not profitable at all. Stick to call20 rule, it will be easier for you to make call or fold decisions with pocket pairs preflop. You won't hit set enough times + you don't know where you are if you hit an overpair. You should fold it preflop or shove if you know that he can call worse hands like 22-99, but it's a higher variance option
