I still think 9.Nd2 is better than Bxd4. That pawn can't be saved without seriously weakening your position, so I'm in no rush to take it. Nd2 develops a piece and keeps my bishop on g2, a good square for it for now. It was a good game and I think you were better until Nb4? I then think h6 was bad as it lost a pawn, and of course Rxa2 was bad as it lost the knight. As you were down in material, exchanging rooks on move 29 was probably not the best choice. You still had chances though in the endgame as I played less-than-stellar moves. I think you should have taken my pawn on move 38, as you should exchange pawns when down. On move 40, Qxf5! would have drawn the game. Although you generally shouldn't exchange pieces when down, I think the endgame would be drawn as you had a pawn for my bishop. Despite my material edge, I doubt there was a way to convert that to a win. 42 Kh6 may have allowed you to keep the draw as well. GG, and GL in the future.
