At least I offered him a draw in the initially endgame.
you missed 60 qb3# but good game
I'm not even sure why they were playing rapid. Why play rapid if you're planning to use 2 minutes and 54 seconds of your time by turn 62 (and the end of the game)? With that in mind, I don't think they would be mad at all, it's not like they were try-harding.
They seem to use no time every game, and they have an 1850 rating regardless, that's pretty good.
Edit: Oh, I didn't even pay attention to the fact that they are 2000 in blitz, that explains it.
I did a same game irl, I offered my opponent a draw and finally I mated him. The endgame was a queen endgame too.
