if a grignard can be used to attack an epoxide, why can't it be used to attack a regular ether?

What kind of reaction do you think would happen between a Grignad and ether? Ring opening can occur between a Grignard and an epoxide, nothing happens between a Grignard and ether. This is why ethers are good solvents from Grignards.

Angle strain makes it easy for Grignard to attack epoxides. Other forms of ether are pretty stable and most are free of angle strain.

An Ether has no acidic protons for the grignard to attack.
