[Archie Comics] Can someone explain to me the dynamic between Archie, Betty and Veronica?

So these two girls both adamantly chase Archie and seem to be totally in love with him. Do the comics go into why at all or is it just kind of the way it is? 

Also they seem to be good friends, are they rivals and competitive with each other? How does their dynamic work?

It's all about sex and manipulation.

Archie is a straight male.

Veronica is a bisexual female who prefers women.

Betty identifies as a straight female but is secretly bisexual with a preference for men.

Betty and Veronica are friends.

Archie wants to be with Veronica. Veronica wants to be with Betty. Archie knows this, so he dates Betty in order to get closer to Veronica.

Veronica knows Archie's plans and plays along, figuring that one way to get into Betty's pants is through Archie, so to speak.

Betty finds herself oddly attracted to Veronica but chooses to be with Archie because that's how she was raised. She has every reason to shut Veronica out from her life but she doesn't because of this odd attraction.
