Welcome to the 1.e4 world of joy, heartbreak, euphoria and misery.
You will rejoice this day and yet there will be times when you will swear you will never play 1.e4 again.
I followed the first few moves in my head, That Be2 - Bh5+ getting a Knight to f7
is a manoeuvre I'm familiar with in the Latvian Gambit but there was something different about it.
I skipped through the game and saw the irony.
Black has played d5. In the Latvian line the d-pawn is on d6. Here.
You jumped onto f7 with the Knight.
Only when you are in check do you a limited number of replies.
Here you are not in check, you are not forced to play Nf7.
The move you have given up. 8.b3.threatens Ba3+ The King goes to d7 and Ne6 wins the Queen.
Not sure if Black would have spotted that, chances are he would have played 8...Rg8
anticipating you playing the Knight fork on f7 which you still threatening to do.
Here after he played 14...Bb5.
You hit the Bishop with 15. a3. There is a better move.
In time you will learn that in 1.e4 e5 openings when things are ragged and you
have a King on the hop moves like 15.a3 have nothing to do with where the action is.
Playing 1.b3 does not really put you in a position to punish tactically lack of
development so you are a wee bit short on lack of development attacking ideas.
But they will come. (but be ready to get you hands burnt in the learning process.)
Look at the Black King and Queen. Just imagine that e4 Knight going to f6.
15.f6 opens up the files and diagonals and 16.Qg4+ is a massive threat..
15...Nxf6 (what else) 16.Rxf6 and Black cannot take back due to 17.Nxf6.
Have fun with 1.e4. You are in excellent company.
