If you were aware that you were 70/30 down, what motivated you to continue on the turn? Are you sure it was a game between friends? I think I would have folded. I'm not a fan of playing real poker with friends, but I guess it's just a matter of personal taste.
Apart from that, I think your hand is pretty weak in preflop, maybe 7-8s I would play it, but off suits I don't think I can play it on short or long tables.
On the flop you have a kicker that protects you less than 50% of the time, and there are many combos of overpairs that beat you, I suppose you thought this guy could bluff here with connected broadways like AK; AQ; AJ, but I wouldn't bother to fold on the flop either, with friends.
Greetings.
