you should just call his minraise. you aren't looking to get your stack in here at all unless you know he is really bad. re-evaluate on turn and river and look to play a small-medium sized pot most of the time.

whats up with the 3bet to 40...way too big - make it 30.
once he min4bets over your big raise, he's made it pretty obvious he likes his hand. you have no fold equity and youre behind everything he can have except for a draw which he decided to go crazy with. essentially, the way the hand played out, i think you should be folding to the 4bet.
