Attack on King side castle using Queen and Bishop

This is a standard Giuoco Piano style game.

Black staged a very good attack on king's castle using his queen and bishop. I need to learn to fight against that.

1. e4 e5 2. Nf3 Nc6 3. Bc4 a6 4. d3 b5 5. Bd5 h6 $2 {Crafty (score 3.56 at depth 8) thinks this is not a good move} ({Crafty suggests:} 5. ... Bd6 6. a4 bxa4 7. Ng5 Nh6 8. Rxa4 O-O 9. O-O $14 {(score 0.74 at depth 8)} ) 6. Bxc6 $2 {Crafty (score 1.13 at depth 8) thinks a good move has been missed} ({Crafty suggests:} 6. Nxe5 Nxe5 7. Bxa8 Qh4 8. O-O Nf6 9. Bd5 Bc5 $18 {(score 3.56 at depth 8)} ) dxc6 7. O-O Qf6 8. h3 Bd6 9. Be3 Qg6 10. Nh4 Qf6 11. Nf3 Be7 12. Kh2 g5 13. Rg1 g4 14. hxg4 Bxg4 15. Nbd2 Qg6 16. Nh4 $4 {Crafty (score -6.05 at depth 9) thinks this is a blunder} ({Crafty suggests:} 16. Re1 Nf6 17. a4 Rg8 18. Kg1 Qg7 19. Qe2 Nh5 $15 {(score -0.39 at depth 8)} ) {I resigned} 0-1



6. Bxc6 -> As crafty suggests, I should have gone for Nxe5

Update: Looks like I could have simply avoided most of the mess using 10. Kh2
