TPGK and Flush-Draw against Maniac

I'm at a loss here. Villain is very loose and very aggressive post-flop although I only just met him, so he could be running hot. I'm not sure about boosting the flop anymore. I think I could have 12 clean outs. But there is only one caller. After the 3bet on the turn he is obviously not scared. So I guess I'm spewing badly on the river when I hit my 2pair. Should I have just called down or am I ahead a good # of times here?
