Answers.Text: Thanks, but I played 4.Qe2 to exchange queens so that black cannot castle. But stockfish did not allow me to do that. And yes, 13. c3?? is really a mistake, I did not see it at that time.

  Main errorrs :
  
  * 4.Qe2? This prevents you to develop your bishop and eventually you had to move your Qeueen out of the way in move 10.Qd2
  * 13.c3? The pawn on d4 was under no immediate attack , you lost your a2 pawn of your castle (weakening your queenside and eventually getting attacked).
  * 20.Bb5 Do not get greedy for pawns when your king is coming under attack due to weak queenside pawn structure .
  
  Overall , the weak Queen move in the start over the developing 4.Be3 made the difference . Eventually the queen had to be moved away and out of the gameplay .

  The first mistake you made was playing against Stockfish. Modern engines are so strong (and have been ever since at least Fritz 5!) that you learn *nothing* from playing them. They'll punish all your tactical mistakes (and at 1000 Elo you make plenty), but you'd get much more useful tactics training out of just doing exercises.
  
  If you want to improve your game you should seek out human opponents somewhat above your level (100-200 Elo points) instead.
