Unless he has 98s or any kind of combodraw the 6 didn't change much, but with all these draws out there not betting gives your opponent a hell lot of ways to play the hand in a way that harms you more than it will help you. I like a bet and since you said he is that aggro I think you need to call as well. Unfortunately the way the hand played down he will never have a set or 2pair here so the only hands that are possible are straights, draws or weaker toppairs... Since there are only few straightcombos I don't think you can get away. The other problem is that I don't think he perceives your hand as a bluff after that action all too often so his raise isn't air too frequentlyx as well.. kinda ugly but bet/call seems best
