I am drawing a simple graph with tikz. This works OK but when I have two edges going in opposite directions between a pair of nodes I get one arrow with two heads (for example between nodes B and D below). How can I get two arrows? Here is a MWE:

usepackagetikz
usetikzlibraryarrows.meta,positioning
usepackagetkz-graph
usepackagegraphicx
begindocument

begincenter
begintikzpicture[auto,node distance=2cm,thick,main node/.style=circle,fill=blue!20,draw,font=sffamilyLargebfseries, scale=2]

Here is a proposal using the calc library to shift the paths by some amount away from the center. Of course, if you do that very often, you may write a macro for that. Or you just bend the paths, as illustrated in the arrows between the B and D nodes.

Thank you, this definitely works. I am surprised there isn't a "less clever" solution though somewhere within a tikz library.

Here are two slightly different syntaxes that give the same result.
The circular placement option allows you to place the nodes on a circle. As there are 5, to draw a regular pentagon, it is enough that the angle is equal to 360/5=72°, its radius is given by radius=40mm.
The clockwise=5 option gives the same result in abbreviated form.
To place arrows, with the quotes library, simply place the text in quotation marks B->["3"]C.

To build graphs, there is the graphs library.
Here are two slightly different syntaxes that give the same result.
The circular placement option allows you to place the nodes on a circle. As there are 5, to draw a regular pentagon, it is enough that the angle is equal to 360/5=72°, its radius is given by radius=40mm.
The clockwise=5 option gives the same result in abbreviated form.
To place arrows, with the quotes library, simply place the text in quotation marks B->["3"]C.
documentclass[tikz,border=5mm]standalone
usetikzlibraryarrows.meta
usetikzlibrarygraphs
usetikzlibraryquotes
begindocument
tikz[>=Straight Barb[length=6pt,width=8pt],thick]
graph [circular placement, group polar shift=(-72:0), radius=40mm,nodes=draw,circle,font=sffamilyLargebfseries,fill=blue!20]
B[label=$infty$],E[label=60:$infty$],D[label=-90:$infty$],C[label=-90:$infty$],A[label=120:$0$],
A->["-1"]B->["2"] E->["-3"] D->["5"] C,
B->["3"]C,
B->[bend left=10,"2"]D,
D->[bend left=10,"1"]B,
A->["4"]C
;
tikz[>=Straight Barb[length=6pt,width=8pt],thick]
