SUMMARY

Electric attraction at subatomic scales is explained through Quantum Electrodynamics (QED) and Feynman diagrams, which represent interactions between charged particles. When like-charged particles interact, they exchange photons, resulting in repulsion due to momentum conservation. For a comprehensive understanding of both attractive and repulsive interactions in QED, refer to Zee's "QFT in a Nutshell, 2nd ed." Specifically, section I.5 provides a readable overview of the mathematical framework involved.

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.
