Only time to note one small detail. After her 44...Kh7 in the game, you might have played Bxh5, which cannot be captured or Rxh5 mate. Then the Bg4 retreat is a sturdy outpost to protect the pawn. Or perhaps your Rd6 might still follow if BL played Rg7 again, but Rf6 instead looked better to me.
It seems BL missed chances to win the d-pawn, or sac the exchange to get it and a won ending. Such as on move 44...Rxf3, then pick up the pawn and simplify so that the q-side pawns give a won Q&P ending.
Nice job to hang onto that difficult game. But like she said, I was wondering why you didnt take that Rook too!? Maybe you were trying to hold it together for so long you just didnt expect she might find a way to lose it?!

Here is a game I recently drew while being material down due to a passed pawn. I'm wondering if there are winning tactics I missed:
