<human>: I plan on breaking up with my gf this week, but I don't know how.

I know that it's shitty to break up over text message. I also kind of know not to do it over the phone. But for the past few days I have been dodging my gf of 2 years. We are supposed to meet up tomorrow, and I'm supposed to help her move into her college apartment.

I was gonna try to dodge her until tomorrow when we meet in person, but she's just been blowing up my phone and nagging me to talk constantly. She wants to talk on the phone tonight and I'm contemplating do it then, but I don't want to be shit-ass about it.

Can you summarize the given text in a few sentences?
<bot>: Do you think it's a no-no to break up with my gf over the phone, similar to how it's considered rude as hell to do it over text?
