So for context: we have been together for a bit over 5 years now. I’m fresh outta college and she has just moved out to a town almost 1000km away from me. A flight so see her costs more than 100 dollars and I still don’t have a job. 
Furthermore she has more 5 years to go and wants me to move in with her, I have other plans as I am currently applying to join a masters/PhD program abroad, so we need to break up. Despite this, I love her very much and am wondering if it’s too much of an asshole move to break up with her by text since it’s our primary and most used mean of communication like 99% of the time. The best I could do is to do it by phone, but I think both me and her will hate it since we have previously, multiple times, expressed our dislike to talk on the phone.

Anyway, will I be the asshole if I break up like this?
