People are extremely judgmental and ignorant when it comes to Archie, he basically gets blamed for everything.
People constantly call him a fuckboy; let's look into that a little bit:
Very first episode of the show, Archie and Veronica ciuman in secret, but it's both of them who goes for the ciuman and it actually so happens that Archie is the first to say "We shouldn't do this" = Archie gets all the blame
1x09; Cheryl is the one ciuman Archie, and he's not okay with it = Archie gets all the blame
For half of the tampil pretty much, Archie and Veronica have been together and stayed true to each at this point.
The latest episode; If anda watch the scene with Betty and Archie again, Betty is the one going for the ciuman here = Archie gets all the blame
When 2x08 ended; everyone immediately hate and judge Archie for that last scene, I do admit it looked weird of course, but if people actually used their minds for a detik instead of being so quick to judge, Archie and Betty had both broken up with Veronica/Jughead, they've been best friends since forever, it's very natural that anda turn to an old friend/your best...
