Also a reminder for anyone reading these comments that chess should be fun! Don't let psychological hangups like thinking u need a good memory, thinking you need to study openings, have a certain level of skill, or need to play a certain format (like avoiding blitz because it is "bad" for your game or thinking OTB is more important) stop you from playing chess! The only rules for how to play chess are the rules of the game; all the other stuff e.g advice about how to get good are just things people make up. Learn and play however you want and in whatever way brings you the most joy! Chess is a game and it is meant to be fun and not be taken seriously
It doesn't take extreme memory on your friend's part either if you keep falling for the same trick. It would take extreme memory for him to have something prepared against every plausible option you could choose.
If you're losing 10 games in a row to a specific opening trap then that falls into the "fool me eight or more times" category :)
