Should I have still have called or bet at the end. I had two pairs, and i was thinking later that i think the player not only had a 7, but probably a full house also. Did i make a bad play on any of the streets?

Well it's more difficult to analyze because you're playing a No-Limit game, and I don't think Hi/Lo games lend themselves well to any format other than limit or a narrow spread. But you were certainly right to continue with your draw on the flop and the turn. I probably would have bet less on the turn so I could have thrown out a small bet on the river as well here. It seems likely from your opponent's betting pattern that he also missed a low draw but knows you missed too and wants to take the pot away from you.
