Well to be honest they were single for such a short time, and then to immediately kiss Betty is just disrespectful. Now if Betty wasn't Veronica's good friend, okay fine. But she is her best friend and Archie knows this and so does Betty. It was selfish and cruel.

I think the supposed payback of Veronica and Jughead was tastelessly written. It was unneccesary and to be honest if you would find out your ex boyfriend and best friend kissed each other so soon after your break up, you wouldn't be pleased either. I would end my friendship right there and then if I was Veronica because Betty only thought of herself, same goes for Archie.

Like you said, the season 4 thing made me see Betty and Archie in a very bad light. I honestly dislike both of them for what they did, hopefully Jug and Veronica end up with someone who deserves them.
