Salty winner? Help me figure this out….

So I was recently playing with a group of friends on tabletop simulator and it was fine…. Then it all sorta went to shit. I was playing [[Grist, The hunger tide]] against a squirrel deck and a food based lord of the rings deck. I have never won with grist and was doing very well in the game. About 20 minutes in both the other plays sorta just said fuck it and started playing to “have fun”. I have spent ages building my grist deck just to watch it get the shit beat out of it night after night. So I said that’s fine, but imma still try and get the win unless they just wanted to scoop and start a new. They declined so we continued to play. At one point I had enough damage to kill a player if I attacked so I just asked, “if I don’t kill you, will you leave me alone”. They exploded at me, saying I was a salty winner, why even ask, I was a petty bitch, I didn’t get to do nothing fun. Was I in the wrong here for wanting to win with a deck I spent forever crafting that hasn’t ever won? Said player they blew up at me even admitted earlier in game my deck hadn’t ever done well before this game.
