How does electric attraction work at subatomic scales?

[Antineutrino]

TL;DR

What is going on in electric attraction Feynman diagrams?

In Feynman diagrams, I believe two like-charged particles will "blast" one another with a photon, thus pushing each other away because of the law of conservation of momentum. How would this work for electric attraction?

A Feynman diagram is not a picture of what gets "blasted". It is shorthand for a term in a mathematical calculation.

It's a bit "risky" to ask for verbal explanations about subatomic phenomena and/or their mathematical description. As Vanadium 50 said, Feynman diagrams fall into that category.

However, if you only worry about how to describe both attractive and repulsive events in QED, you can find a nice passage in Zee's "QFT in a Nutshell, 2nd ed.", section I.5; it's on the math side, but the text between the equations is readable.
