Does anybody else have a friend they play over and over, it feels like that’s lowering my ELO?

I have played chess on my chess.com app for almost 800 days in a row, I have been trying to learn new things, new openings, I watch gameplay, I play over the board every day, my ELO has not gone up in ANY of my rankings in those 800 days. I feel like my set in stone chess brain isn’t changing at all and it’s frustrating to see it happen in real time. I play multiple speed variations of the game, and nothing is changing. Anyway, I play my one long distance friend daily and my dad over the board every single day. Is it possible playing the same people repetitively can make me worse at the game?
