@estragon89my 2 cents:
The french is not busted, but it is difficult to play. I did use it for many years though against weaker opposition in order to generate winning chances in a better endgame. But even after having had much success with it, i gave up on it, when i noticed some of the very dangerous attacking lines, white can choose, and i was not good enough to defend blacks position there.
But at the playing level you seem to be at, i guess you were attracted to get a comprehensible position soon without too many positional complexities. In that case, achja's suggestion (apparently named Fort Knox) really is a good option. I knew about it even back in the days, but wanted to keep more pieces on the board (none of your worries, i guess).
I would like to point out, that the french is more difficult, if your opponent knows in advance, what kind of system you are going to play and can prepare accordingly. If you are going to face such opponents, i would suggest to have another opening in reserve to have a safe way out.
From the looks of your example game, i immediately thought, that the line did not seem to be too different from a caro-cann. And the Caro is an excellent equalizer, not too familiar to most intermediate players.
Hoping, this helps a little.
Btw: Everyone of us did fall victim to a vicious attacker once in a while, just like you this time. Good, that you are trying to learn from it. And you probably know, that such an experience is not really caused by a good or a bad opening, but by getting surprised by a versatile attacker. - Just saying: you *could* just continue with your line, knowing, how to properly defend now.
