so, the pawn move 3 squares forward and i played hxg5!!
I played hxg5 here. there were some other pieces on the board, but you get the point
By the way, there is a lesson showing exactly the black and white pawns on g and h files where en passant is valid. Give it a look https://www.chess.com/lessons/playing-the-game/en-passant
You have a daily rating of 1862, so trolling?
And his blitz is 1600+, I would expect him to know these things but then again, there is so much confusion around this rule I'm giving him the benefit of the doubt.
I am legitimately confused

You can ONLY use the en passant rule if the black pawn has just used the special move of moving forward 2 squares from its starting position and you have a pawn next to it (for example, if you have a white pawn on h5 and the black pawn goes g7 -> g5, then you can do hxg6). However, in your example the only way the black pawn could end up on g4 square is by either making 2 moves (g7 -> g5 and then g5 -> g4) or 3 moves (g7 -> g6 -> g5 -> g4). In both of these cases you may no longer use the en passant rule.
but he played g4!
